The Senate Majority PAC, a top outside group backing Democratic Senate incumbents and candidates, announced Friday that they will stand behind former Tennessee Gov. Phil Bredesen despite his support for Judge Brett Kavanaugh.

The group said that they will also continue to back Sen. Joe Manchin, D-W.Va., if he votes Saturday for Kavanaugh, over the opposition of all the other Democrats.

"Senate Majority PAC supports Phil Bredesen and Joe Manchin. They are the only candidates with an independent record of getting results for Tennessee and West Virginia," said Chris Hayden, an SMP spokesperson. "They're both winning these races because of their record."

The news comes after Priorities USA, another top Democratic outside group, said Friday that they would not support either Bredesen or Manchin, assuming he votes for Kavanaugh.

Bredesen announced Friday that he would vote for the judge despite Dr. Christine Blasey Ford's testimony, which he admitted made it a "much closer call."

"I believed that Judge Kavanaugh initially met this test, and I was prepared to say ‘yes’ to his nomination prior to Dr. Ford’s coming forward," Bredesen said in a statement. "While the subsequent events make it a much closer call, and I am missing key pieces of information that a sitting senator has, I’m still a ‘yes.'"

Manchin, meanwhile, still has not announced how he plans to vote in Saturday's final vote and kept his vote Friday morning close to the vest until he stepped on the floor. Sen. Susan Collins, R-Maine, is expected to announce her decision Friday at 3 p.m.
