Sen. Chris Murphy, D-Ct., scoffed Friday at the news that Senate leadership would delay the confirmation vote on Supreme Court nominee Brett Kavanaugh for one week to allow the FBI to perform a supplemental investigation of allegations the judge sexually assaulted a woman in the early 1980s.

It’s funny because Murphy was gung-ho for an FBI investigation before Republicans moved to make it a reality. It's worth pointing out now, just in case you were wondering how unserious Democratic lawmakers are when they say they want a fair and thorough investigation of the allegations against Kavanaugh.

As recently as Wednesday, Murphy was positively eager to have the bureau investigate claims that Kavanaugh tried to rape a woman when they were both in high school.

“The only reason not to do an FBI investigation is that Republicans want to rush Kavanaugh through. There is no rush. The three women are willing to testify under oath and anyone who has information to dispute the claims should be too,” the senator’s office tweeted on Sept. 26., referring to the GOP's reluctance to refer the entire matter to the federal law enforcement agency.

Earlier, on Sept. 23, the office of Sen. Dianne Feinstein, D-Calif., tweeted, “Thursday's hearing should be canceled in light of a disturbing new allegation of sexual misconduct against Brett Kavanaugh. The FBI must investigate ALL allegations.”

Murphy was very excited about this idea. His office responded at the time, “Senator Feinstein is right. This is a lifetime appointment — there is zero reason to rush. The committee and the FBI should do a full investigation, giving Republicans time to do some soul searching.”

But after news coverage suggested Friday afternoon that there would indeed be a supplemental FBI investigation of Kavanaugh, which is exactly what Democratic lawmakers have been insisting on over the past few weeks, Murphy cooled almost immediately on the idea.

“Yes,” his office tweeted, “of course there should be an FBI investigation. But whatever they find doesn’t change the fact that Kavanaugh, especially after his performance yesterday, is the most dangerous Supreme Court pick of our lifetime.”

Murphy’s remarks came not long after Sen. Jeff Flake, R-Ariz., announced Friday he would vote on the Senate Judiciary Committee to move Kavanaugh’s nomination to the full U.S. Senate, but will only support him on the floor if leadership delays the final confirmation vote for one week to give the FBI time to investigate the allegations made against the Supreme Court nominee.

Sen. Lisa Murkowski, R-Alaska, announced her support for Flake’s plan almost immediately, leaving Republican leaders with no choice but to go along with the compromise. Senate Majority Leader Mitch McConnell, R-Ky., can’t afford to lose more than one Republican vote. If Flake and Murkowski stick to their guns, Kavanaugh goes down in the Senate. Unsurprisingly, Senate Whip John Cornyn, R-Texas, confirmed Friday that leadership agreed to delay the vote so the FBI could perform a supplemental investigation for up to one week.

Considering Democratic lawmakers spent nearly all of their time during Thursday's congressional hearing with Kavanaugh trying to get him to say he supports the FBI investigating the allegations against him, you’d think someone as high-profile as Murphy would welcome the developments kicked off by Flake.

But for people like Murphy to welcome it, he’d have to be serious about a fair and thorough investigation. Murphy’s response, which is likely to be the first of many from his colleagues, suggests he is not serious, nor has he been for this entire ordeal. For Democratic lawmakers, this isn’t about what’s true or standing up for victims of sexual abuse. It’s about keeping a conservative judge from taking the Supreme Court’s swing vote seat.
