Google parent Alphabet has followed with plans of its own to shrink its workforce. Billionaire Elon Musk does much of his communication through Twitter, the troubled company he now owns, but on Friday Musk appeared in court on the witness stand in a trial over tweets that may have crashed the stock price of Tesla. Musk tweeted he claimed he had funding secured to take the company in private. This left many stockholders with big losses as investments were made on the information. Mark feige is a retired securities litigator. This is an unusually straightforward case. You have a couple of tweets that are as close to black and white as you can. Did he, in fact, have funding secured or not. So it's much simpler than the typical securities fraud case. Musk's testimony continues on Monday. Social media giant YouTube and its parent company Google will stand before the Supreme Court next month to defend its algorithms under a law known as section two 30. The decades old regulation gives them immunity from third party posters who violate the decency act. The lawsuit is being brought by a family of a terrorist attack victim, the family says YouTube helped promote and spread ISIS ideology. Facebook whistleblower and data engineer Francis haugen believes those algorithms aren't covered and these companies can do better. We have tools, but all these things decrease usage. You know, they make the companies a little bit less money. Now Gonzales was killed nearly 8 years ago in a 2015 terror attack in Paris, her parents have brought the suit to the Supreme Court.

What we need are armor, heavy armor, tanks, because tanks lead the push. They punch through the lines, they have the mobility, the firepower, and the protection to do so while safeguarding the force. And that's the critical missing element right now. For the most part, the Brits have promised to provide 14 challenger tanks, but what you need are tanks and the triple digits to make this real. So Mark Esper, what is the timeline as we work this out with Germany, whether it's leopards, M ones, whatever end up there. How much time do we have before it's too late? Not much. I mean, look, time is now. That's why I think we are moving now. It takes at least for the United States, of course, to ship them, would take weeks. You have to get them to the units within Ukraine. You have to train up the soldiers, not just to operate them, but to maintain them. So this process could take several weeks a couple of months, and then you look at the timeline for the year. When does the weather start improving for either the Russians to conduct an offensive, whether Ukrainians to beat them to the punch. And again, while it's important that we provided Bradley's and strikers, you would never send those vehicles into a battle against Russian armor. You have to leave with your own tanks. And that's where the Germans become the critical component here. I want to ask you specifically about the M1 Abrams tanks. Number one, you know, they're very expensive to maintain. It also involves a lot of training that would be necessary. They have a jet engine essentially in them and as I understand burn three gallons to the mile. Is that even practical for Ukraine? No, I think the German leopards are the better choice here. I've been critical of the administration for being behind the curve when it comes to sending other weapons systems and air defense systems and whatnot. But in this case, they're right
