Frustration on Capitol Hill is mounting after a string of aerial objects were shot down over U.S. and Canadian airspace in the last few days, raising a long list of questions that lawmakers say President Biden should publicly address. 

Three unidentified flying objects (UFOs) have been shot down over North America since Friday, and the Pentagon has provided little information on what the objects were or where they came from. 

“The president owes the American people an explanation, direct and on camera, of what we know about these ‘objects’ and what steps he’s taking to protect America’s sovereign airspace,” Sen. Tom Cotton (R-Ark.) said in a Monday statement.

Sen. Marco Rubio (R-Fla.), the vice chairman of the Intelligence Committee, also joined in the calls for President Biden to address the nation, noting the unprecedented nature of the military shooting down aircraft in U.S. airspace. 

“NORAD’s been around almost 65 years,” he said of the command in charge of patrolling U.S. and Canadian airspace. “We’ve never shot anything down, and in eight days we’ve shot down four things. That’s a pretty big deal. It doesn’t happen every day.”

Rubio added in a tweet: “Americans need to hear directly about this from their President today.”
