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.

Why it matters: Quibi had struggled to hit its subscriber growth targets amid the global pandemic. The app launched six months ago.

Security has been stepped up in Washington, D.C., and state capitols across the U.S. as authorities brace for potential violence this weekend.

Driving the news: Following the Jan. 6 insurrection at the U.S. Capitol by some supporters of President Trump, the FBI has said there could be armed protests in D.C. and in all 50 state capitols in the run-up to President-elect Joe Biden's inauguration Wednesday.
