Republicans will have full control of Congress and the White House, giving them their best shot yet to make big moves on immigration and tax cuts.

In two races, Democrats are increasing their leads. In another, the Democrat is chipping away at the Republican incumbent’s edge.

In one of the most competitive and closely watched Congressional races of this election cycle, Republican Rep. Mike Garcia conceded to Democrat George Whitesides, a political newcomer, on Monday, Nov.

Republican Senators John Thune of South Dakota, John Cornyn of Texas, and Rick Scott of Florida were all vying for the top leadership spot in the U.S. Senate. However, in a closed-door vote on Wednesday, Thune was selected as the winner.

: Republicans will retain control of the House of Representatives with a razor-thin majority in the next Congress. The AP has not called the race for control of the chamber, but House Minority Leader Hakeem Jeffries conceded that the GOP would have a majority.

If Republicans keep the House majority, that would give the party control of all three branches of government after the GOP won control of the U.S. Senate and Donald Trump won the presidential election.
