"Following a call from Trudeau to President Joe Biden on Saturday, Biden authorized that U.S. aircraft take down the new high-altitude object and a U.S. F-22 shot it down with a sidewinder missile, Ryder said.

I'm scratching my head here. There is no way that US military aircraft would shoot down a balloon without the president's authority. Come on, now, chaps!
