Republican Sen. Thom Tillis won reelection against Democrat Cal Cunningham in North Carolina’s Senate race.

Cunningham, a former state senator who became embroiled in a sexting scandal late in the campaign, on Tuesday conceded to Tillis after election night tallies and subsequent ballot counting left him more than two percentage points behind.

“I just called Senator Tillis to congratulate him on winning re-election to a second term in the U.S. Senate,” Cunningham tweeted.

The race to declare a winner seven days after the general election kept Republican and Democratic lawmakers on edge, as the balance of the Senate still remains in question. With Tillis re-elected the Senate stands at 49-48 in favor of Republicans, with Alaska still outstanding and two Georgia seats that went into runoffs.
