Separately, the Senate Judiciary Committee made public late on Sunday a previously unreleased interview with Kavanaugh from September 26, before a public hearing with Ford, in which he denied all the allegations against him and committee Democrats declined to ask questions, saying they felt the FBI should investigate the allegations.
McConnell referred to a memo from Arizona prosecutor Rachel Mitchell, who told Judiciary Committee members after being brought in to question Christine Blasey Ford at Thursday's hearing that "I do not think that a reasonable prosecutor would bring this case based on the evidence before the committee".
"The former five-term senator from MA also called it incomprehensible" that the Judiciary Committee had not sought to speak with Mark Judge, the friend of Kavanaugh's who Ford identified as the only other witness to her assault.
When asked what he thought the chances were that after the FBI wraps up its investigation, "we are going to be in exactly the same place", Flake responded: "There is a chance that that will happen", but added he does think progress can be made.

Allison , 70, of the University of Texas Austin, studied a known protein and developed the concept into a new treatment approach. The duo will share the Nobel prize sum of nine million Swedish kronor (about $1.01 million or 870,000 euros).
Kavanaugh has denied all of the allegations.
And Flake, who is retiring after his term, riled the already fraught confirmation process after he announced last week that he would not vote to send Kavanaugh to the Supreme Court unless the Federal Bureau of Investigation is allowed one week to investigate. She said, "I'm waiting to see what the results are".
Flake said Ford offered "compelling, credible testimony", but he also found Kavanaugh's "impassioned, very raw defense" to be effective.
In March, Flake told New Hampshire Republicans that someone needs to stop Trump in the 2020 presidential contest.
"It's when we try and avoid compromise and take partisan advantage and do things because we have the numbers, especially when we are as terribly and closely divided as we are now that we begin to do serious damage to the country", he said.
"It has not been in my plans to run for president, but I have not ruled it out", Flake said at the time.
"Any nominee that lies to the committee, that is disqualifying", Flake told reporters after delivering a speech in New Hampshire, the state that hosts the nation's first presidential primary election. "I think that's the height of hypocrisy". I want it to be comprehensive.
