The federal government shut down at midnight after a deadlocked Congress failed to reach a deal on funding. CNN's Brian Todd reports from Ronald Reagan Washington National Airport, where TSA agents and air traffic controllers are working without getting paid.

As the government shutdown continues, tensions between Democrats and Republicans are rising on Capitol Hill. On Wednesday lawmakers broke out into open hostility as Rep. Mike Lawler (R-NY) and House Minority Leader Hakeem Jeffries (D-NY) got into a heated verbal confrontation over the shutdown. #cnn #governmentshutdown #lawler #jeffries
