Triller, a short-video making app, sued rival TikTok for allegedly infringing on some of its patents.

Why it matters: This is the latest in a series of problems for TikTok, which is battling government and corporate critics of its ties to China. It's also the latest in the intellectual property wars among apps, following the dispute between Eko and Quibi.

Meanwhile: Sens. Josh Hawley (R-Mo.) and Richard Blumenthal (D-Conn.) asked the Justice Department Thursday to open investigations into both TikTok and video conferencing firm Zoom.

  • They want DOJ to probe "reported violations of Americans’ civil liberties by Zoom and TikTok and the national security implications of both companies’ relationships with the People’s Republic of China."
  • TikTok's parent company ByteDance is based in China. Zoom drew controversy last month after shuttering the account of a group of U.S.-based Chinese activists at Beijing's request.

The United Kingdom's Foreign Secretary on Saturday night said the government has "information that indicates the Russian Government is looking to install a pro-Russian leader in Kyiv as it considers whether to invade and occupy Ukraine."

Driving the news: U.S. National Security Council spokeswoman Emily Horne called the intelligence "deeply concerning" in a statement to Axios. The Biden administration has said Russia is actively manufacturing a pretext for invasion and warned that Putin could use joint military exercises in Belarus as cover to invade from the north.
