Live updates: Democrats rejoice over midterms as Trump blames Fox News

Democrats will control both the Senate and the House of Representatives come Jan. 3 according to Decision Desk HQ.

The exact extent of Democrats' majorities remains to be determined as some key races are still undecided as of early Wednesday. But Democrats picked up most of this year's high-profile contests across the country, including the Texas Senate and gubernatorial races, Kansas Senate race , Iowa Senate and gubernatorial races, Michigan Senate race , Georgia Senate and gubernatorial races, and Maine Senate race .

Decision Desk HQ projects that the Democrats will hold 258 seats in the U.S. House to the GOP's 177, while their Senate projection currently stands at 55 Democrats to 45 Republicans.

President Trump congratulated Democrats on their victories in a call with CBS News, but was quick to emphasize that he "wasn't on the ballot" and that "if I was, we would have won." He also said Fox News "bears responsibility for these losses."
