There may be a senator somewhere in the nation’s capital whose mind was changed by the FBI’s seventh background investigation of Supreme Court nominee Judge Brett Kavanaugh (pictured above), but he or she is keeping a low profile.

And the bitter debate rages on.

“There’s nothing in it that we didn’t already know,” Senate Committee on the Judiciary Chairman Chuck Grassley (R-Iowa) said after reading the FBI report delivered to the Senate and White House early Thursday.

“These uncorroborated accusations have been unequivocally and repeatedly rejected by Judge Kavanaugh, and neither the judiciary committee nor the FBI could locate any third parties who can attest to any of the allegations. There’s also no contemporaneous evidence.”

Grassley added: “I trust that the career agents of the FBI have done their work independent of political or partisan considerations. That’s exactly what senators from both sides asked for. Now it’s up to senators to fulfill their constitutional duty and make a judgment.”

Sen. Dianne Feinstein (D-Calif.), the judiciary panel’s ranking minority member, rejected the report as not credible because, she claimed, the FBI was constrained on time and scope.

“Deborah Ramirez’s lawyer said he was unaware of any corroborating witnesses who were interviewed,” Feinstein told reporters after she received it. “I had the opportunity to read some but not all of it. It looks to be the product of an incomplete investigation that was limited perhaps by the White House.”

Senate Minority Leader Chuck Schumer (D-N.Y.) responded to the report during that same press conference by calling for it to be released publicly along with the White House directive to the FBI launching the investigation. He and other Democrats have contested the lack of transparency when it came to the investigation.

“We had many fears that this was a very limited process that would constrain the FBI from getting all the facts,” Schumer said. “Having received a thorough briefing on the documents, those fears have been realized.”

In fact, the FBI review was “limited in time and scope” as a result of a proposal by Sen. Jeff Flake (R-Az.) that was accepted by Grassley, Feinstein and the rest of the judiciary committee on September 28.

Within minutes after the committee voted on party lines to forward Kavanaugh’s nomination to the full Senate, however, Democrats were criticizing the one-week time limit and demanding that dozens more witnesses and allegations be included in the FBI review.

California psychology professor Christine Blasey Ford became the first of the three women to accuse Kavanaugh of sexual misconduct. She claims he assaulted her while he was a high school student at Georgetown Preparatory School during the 1980s. Kavanaugh was quick to deny the allegations when they first started spreading.

Sen. Orrin Hatch (R-Utah) responded to critics opposing the findings by pointing to their own inaction. Feinstein knew about the Ford allegation for weeks before it surfaced but decided not to reveal it to the public or the committee. Ford had asked her to keep it private. But the letter leaked on September 12, only days before the first major vote on the nomination.

“If not for Senator Feinstein’s egregious mishandling, this investigation could have started seven weeks ago,” Hatch said in a tweet. “Attacking the FBI’s valuable efforts because Senate Democrats chose to keep information from them is a mistake.”

Sens. Flake, Susan Collins (R-Maine) and Lisa Murkowski (R-Alaska) have remained among the few undecided votes on the Republican side. Republicans control the Senate but only by a razor-thin, two-vote margin, making those few votes critically important.

“It appears to be a very thorough investigation, but I am going back later today to personally read the interviews,” Collins said, according to ABC News. “That’s really all I have to say right now.”

The Senate could potentially be voting on the nomination as early as Saturday. Senate Majority Leader Mitch McConnell (R-Ky.) took a major step in that direction by invoking a cloture vote late Wednesday. The motion sets up a procedural vote for Friday, which would then limit debate on the nominee to 30 hours if successful.

“The FBI has completed yet another background investigation on Judge Kavanaugh and delivered its results to the Senate,” McConnell said in a tweet. “The fact is that these allegations have not been corroborated. Not in the new FBI investigation, not anywhere.”

“The new information in the supplemental FBI report does not corroborate the allegations made against Judge Kavanaugh,” Sen. Mike Lee (R-Utah) said in a statement. “I look forward to voting for his confirmation imminently.”

The Republican National Committee (RNC) praised Republicans lawmakers for conducting what officials called a thorough and fair nomination process despite the bitter political debate. The RNC added that after multiple hearings, interviews, and federal investigations, it is time to vote.

“The Democrats’ political spectacle has gone on long enough,” RNC Chair Ronna McDaniel said in a statement provided to LifeZette. “Their delay tactics have done a disservice to everyone involved. Their character assassination has left a partisan stain on the highest court in the land.”

“Chairman Grassley has gone the extra mile to be thorough, transparent, and fair to everyone involved in this process,” Carrie Severino, chief counsel and policy director of Judicial Crisis Network, told LifeZette.

“The unprecedented supplemental FBI report has found nothing of significance to corroborate the current allegations; zero evidence, zero corroboration. It is time for the Senate to put an end to the circus and confirm Judge Brett Kavanaugh to the Supreme Court,” said Severino, whose organization has spent millions of dollars defending Kavanaugh and supporting his nomination.

Sen. Heidi Heitkamp (D-N.D.) disappointed Republicans by announcing her opposition to Kavanaugh Thursday. President Donald Trump carried North Dakota by a huge margin in the 2016 presidential election, so Heitkamp was thought to be one of the few potential Democrat votes for Kavanaugh.

“The process has been bad, but there comes a time when you have to make a decision. I will be voting no on Judge Kavanaugh,” Heitkamp told a North Dakota television reporter.
