After the president taunted Christine Blasey Ford at a campaign rally in MS on Tuesday night they decried his behaviour as "appalling" and "plain wrong", but stopped short of saying that it would influence their vote.
"This vile, mocking attack on a credible, immensely powerfully eloquent survivor of sexual assault is a mark of disrespect and disregard not only for Dr. Blasey Ford but the entire survivor community", he told CNN's "New Day" host Alisyn Camerota.
"An FBI supplemental background investigation that did not include an interview of Dr. Christine Blasey Ford- nor the witnesses who corroborate her testimony - can not be called an investigation", Ford's attorneys wrote. Susan Collins of ME and Lisa Murkowski of Alaska, who are seen as swing votes on the Kavanaugh nomination, also rebuked Trump.
"I wish he hadn't done it", Flake said.
Flake condemned Trump's remarks on Wednesday, calling them "kind of appalling".
Mark Judge, a friend of Kavanaugh's who previously said in a letter to the committee the he did "not recall the events described by Dr. Ford in her testimony" nor did he see "Brett act in the manner Dr. Ford describes", was among those interviewed by the Federal Bureau of Investigation.
The poll was based on telephone interviews with a random sample of 1,462 adults, conducted from September 24 to September 30 -after Kavanaugh and Ford testified before the Senate about the sexual assault allegations - and featured a 3 percent margin of error at 95 percent confidence level.
Their reactions left Republicans concerned that Trump had complicated their effort to cement Kavanaugh's support in a chamber where the GOP holds a razor-thin 51-49 majority.

And speaking at an event hosted by The Atlantic magazine, Trump ally Senator Lindsey Graham of SC said he "didn't particularly like" the president's remarks, adding, "I would tell him, knock it off".
The FBI did not include any conclusions as to whether Ford or Kavanaugh was telling the truth. He has denied the allegation, as has the White House, claiming there are numerous holes in her story. Does the President have any comment on this alleged fraud?
White House counselor Kellyanne Conway on Wednesday echoed the president's newly aggressive approach. "I don't know", Trump said on stage in Southhaven, Mississippi, mimicking and misrepresenting Ford's testimony. That's the only thing I remember.
"And a man's life is in tatters", Mr Trump added. "Vote him up or down". Democratic senators Heidi Heitkamp and Joe Manchin remain undecided.
A final vote on the nomination could come Saturday. Vice President Mike Pence, who would be brought in to break a tie, is due to campaign Monday in Texas for both Senator Ted Cruz and Representative Pete Sessions, but officials with both campaigns braced for changes.
Hundreds of U.S. law professors are signing an online letter addressed to the U.S. Senate claiming that President Donald Trump's Supreme Court nominee Brett Kavanaugh is disqualified from sitting on the nation's highest court.
Democrats have raised concerns that the investigation has been too narrow in scope, and that key witnesses have been omitted.
Senate Republicans now need a simple majority for a vote to end debate on the nomination, which is expected to take place on Friday.
Also interviewed was Tim Gaudette, a high school classmate of Kavanaugh.
