Senate Republicans have re-elected Kentucky's Mitch McConnell to be majority leader when the new Congress convenes in January and starts working on Donald Trump's agenda.
McConnell distanced himself from Trump during the campaign, but says he's ready to work with him.
Senate Democrats, meanwhile, have elected Chuck Schumer to be their new minority leader. The New Yorker will be Washington's most powerful Democrat as the party confronts an all-Republican government led by Trump.
