Waymo, Alphabet's self-driving car unit, has asked a federal judge in California for a preliminary injunction to block Uber's self-driving car project, according to new court documents obtained by news outlets.

Expert testimony: Waymo also filed the sworn testimony of Gary Brown, a forensic security engineer at Google since 2013, according to The Verge. Brown says that according to logs from Google's secure network, Anthony Levandowski, a Google engineer who left the company to start the self-driving car startup Uber acquired last year, downloaded 14,000 files from Google containing proprietary information before leaving the company in early 2016. Brown also names two other engineers, Radu Raduta and Sameer Kshirsagar, who he claims also downloaded proprietary files before leaving Google to join Levandowski.

In late February, Waymo filed a lawsuit against Levandowski's startup and Uber, claiming they stole intellectual property from Google.

What to watch: Uber has called the lawsuit "baseless," so it's likely to try to prove that its own technology is different from Waymo's. Last year, in an interview with Forbes, Levandowski emphasized his team didn't steal any intellectual property from Google and it has "all the logs" to show that.

The clock is ticking for tens of thousands of anxious airline employees, who face mass reductions when the government's current payroll support program expires on Sept. 30.

Where it stands: Airline CEOs met Thursday with White House Chief of Staff Mark Meadows, who said President Trump would support an additional $25 billion from Congress to extend the current aid package through next March.

Four Democratic House committee chairs on Friday asked the Justice Department's inspector general to launch an "emergency investigation" into whether Attorney General Bill Barr and U.S. Attorney John Durham, his appointee, are taking actions that could "improperly influence the upcoming presidential election."

Catch up quick: Last year, Barr tapped Durham to conduct a sweeping investigation into the origins of the FBI's 2016 Russia probe, after he and President Trump claimed that it was unjustified and a "hoax."
