If Kavanaugh overcomes the procedural hurdle, the Senate could then take a final vote on his nomination as early as Saturday.

McConnell pledged earlier Wednesday that the chamber would vote on Kavanaugh this week, despite what he argued were attempts by Democrats to delay or stall the nomination.

“There will be plenty of time for Members to review and be briefed on this supplemental material before a Friday cloture vote. So I am filing cloture on Judge Kavanaugh’s nomination this evening so the process can move forward, as I indicated earlier this week," McConnell said.

The decision to pave the way for a vote on Kavanaugh’s nomination comes as he remains short of the simple majority needed to be confirmed based on senators' public positions.

Republicans hold a slim 51-seat majority, meaning they could lose one GOP senator before they need help from Democrats to get Kavanaugh past procedural roadblocks and confirmed to the Supreme Court.

The senators have previously voted to end debate, even if they didn’t ultimately support the nominee, meaning McConnell would likely have the votes to end debate on Kavanaugh’s nomination as early as Friday.

But Republicans would need two of out of the three swing votes to support Kavanaugh if every Democrat opposes him in order to get the 50 votes needed for Vice President Pence to break a tie and confirm him.

Collins called Trump's remarks “plain wrong,” while Murkowski said they were “wholly inappropriate.”

Republicans appeared confident that, barring an eleventh hour bombshell spinning out of the FBI’s investigation, they would get the votes needed to confirm Kavanaugh.

McConnell added on Wednesday evening that the chamber will receive the background investigation on Wednesday evening and Judiciary Committee staff will be able to brief members.

“This evening, the Senate will receive the results of the FBI’s supplemental background investigation of Judge Brett Kavanaugh. This is now the seventh time the FBI has looked into Judge Kavanaugh’s background. And this information comes on top of what has already been one of the most thorough, most exhaustive Senate reviews of any Supreme Court nominee in our nation’s history," McConnell said.

He added that senators will have the update to the background investigation and the "opportunity to review the investigators’ records."

McConnell's move immediately drew criticism from Democrats, progressive groups and a woman accusing Kavanaugh of sexual assault.

Attorneys for Ford slammed the FBI's investigation for not interviewing Ford or witnesses to back up her testimony.

"An FBI supplemental background investigation that did not include an interview of Dr. Christine Blasey Ford — nor the witnesses who corroborate her testimony — cannot be called an investigation. … Those directing the FBI investigation were not interested in seeking the truth," Ford's counsel said in a statement.

Faiz Shakir, national political director of the American Civil Liberties Union, said McConnell's decision was "premature and rash."

"It is outrageous that the Leader would decide that senators have enough information to end debate when they have not comprehensively reviewed the scope of the investigation or its results," he added.
