TikTok CEO Testifies Before Congress: Here Are Some of the Key Moments

Lawmakers grilled CEO Shou Chew about ties to China and what the app is doing to protect young people.

TikTok CEO Shou Chew on Thursday faced skeptical lawmakers in the US Congress to try to fend off calls to ban the hugely popular video app.

«There are more than 150 million Americans who love our platform, and we know we have a responsibility to protect them,» Chew said in remarks prepared for his appearance before the House Energy and Commerce Committee.

Earlier this month, the Biden administration demanded that ByteDance, the app’s Chinese parent company, sell its stake in the app or face a possible ban. Officials are concerned TikTok could be forced to share US user data with the Chinese government, posing a national security threat. In December, US lawmakers banned the app from government devices. Other countries, including Canada, EU member states and Taiwan, have taken similar steps.

Lawmakers on Thursday repeatedly questioned Chew about ByteDance’s ties to the Chinese government, expressing doubt TikTok would be able to protect US users’ data. They also alleged that TikTok could be used by the Chinese government to influence public opinion in the US.

Though the main thrust of the hearing focused on alleged ties to China, lawmakers also touched on other concerns, including data collection and protecting teens and young people from harmful content on TikTok.

Following the hearing, TikTok spokesperson Brooke Oberwetter said the hearing was «dominated by political grandstanding» and failed to address industry-wide issues.

«Also not mentioned today by members of the Committee: the livelihoods of the 5 million businesses on TikTok or the First Amendment implications of banning a platform loved by 150 million Americans,» said Oberwetter.

Here are some of the most interesting comments from the hearing:

Committee Chair Rep. Cathy McMorris Rodgers, in her opening statement: «Mr. Chew, you are here because the American people need the truth about the threat TikTok poses to our national and personal security. TikTok collects nearly every data point imaginable, from people’s location to what they type and copy, biometric data and more. … TikTok surveils us all. And the Chinese Communist Party is able to use this as a tool to manipulate America as a whole. We do not trust TikTok will ever embrace American values.»

She continued: «TikTok has repeatedly chosen a path for more control, more surveillance and more manipulation. Your platform should be banned. I expect today you’ll say anything to avoid this outcome.»

Chew, in his opening statement: «We have heard important concerns about the potential for unwanted foreign access to US data and potential manipulation of the TikTok US ecosystem. We have addressed them with real action. … That’s what we’ve been doing for the last two years, building what amounts to a firewall that seals off protected US user data from unauthorized foreign access. The bottom line is this: American data, stored on American soil, by an American company, overseen by American personnel. We call this initiative Project Texas.»

Chew, on legacy US data: «We have legacy US data sitting in our servers in Virginia and in Singapore. We’re deleting those and we expect that to be complete this year. When that is done, all protected US data will be under the protection of US law and under the control of the US led security team. This eliminates the concern that some of you have shared with me that TikTok user data can be subject to Chinese law.»

Rep. Buddy Carter, on harmful viral videos like the Milk Crate challenge: «Why is it that TikTok consistently fails to identify and moderate these kinds of harmful videos? Why is it that you allow this to go on? We’ve already heard … from parents who are here with us who have lost children.»

Chew responds: «This is a real industry challenge and we’re working on our…»

Carter: «No, no, it’s not industry. This is TikTok. We’re talking about TikTok. We’re talking about why is it that you can’t control this. … Tell me why this goes on.»

Rep. Darren Soto, on ByteDance ownership: «Mr. Chew, would TikTok be prepared to divest from ByteDance and Chinese Communist Party ties if the Department of Treasury instructed you all to do so?»

Chew responds: «I don’t think ownership is the issue here. With a lot of respect, American social companies don’t have a good track record with data privacy and user security. I mean look at Facebook and Cambridge analytica, just for one example.»

Rep. Neal Dunn asks Chew directly: «Has ByteDance spied on Americans at the direction of the Chinese Communist Party?»

Chew responds: «No.»

Dunn follows up, citing a Forbes article that ByteDance planned to use TikTok to monitor the location of US citizens: «I ask you again Mr. Chew, has ByteDance spied on American citizens?»

Chew responds: «I don’t think that spying is the right way to describe it. This is ultimately…(Dunn cuts off his response.)»

Rep. August Pfluger, on Project Texas: «Please rename your project. Texas is not the appropriate name. We stand for freedom and transparency and we don’t want your project.»

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
