"I feel so badly for him that he is going through this, to be honest with you", Trump said during a joint press conference with Polish President Andrzej Duda.
Kavanaugh was at the White House for a second straight day on Tuesday, but again did not meet with Trump.
"For those Democrats up for re-election from states that Trump carried, they now have absolutely no reason to vote for Kavanaugh".
Democrats had demanded a delay in the committee's vote in order to let the FBI investigate.

"I was a prosecutor, I've done these cases it takes a little time to try to sift through the facts and let whoever it is, the Federal Bureau of Investigation to do some things and I think they need to let this play a little bit", he said.
Republicans responded that reopening the investigation is up to the White House and they are sticking with their plans for a Monday hearing - with or without Ford's participation.
Kavanaugh has forcefully denied the allegations and told a senator that he was not present at the party where the alleged assault occurred. "So it kind of raises the question.do they want to come to (the) publichearing or not?"
Yet a few Republicans have suggested there may have to be a delay, at least in the Judiciary vote on the nominee - which was scheduled for this Thursday - in order to hear from Ford.
But Conway said such testimony "should not unduly delay the vote".
"Collins seems to have forgotten that Brett Kavanaugh is the one who has been accused of a crime, not Christine Blasey Ford", CREDO Action co-director Heidi Hess said in a statement. "What about other witnesses like Kavanaugh's friend Mark Judge?".
Sen. Dick Durbin of IL, the No. 2 Democrat, said Judge is needed "specifically and personally as an eyewitness to the occurrence".
John Feehery, a Republican strategist, says the #MeToo movement is not just about justice - it's also about punishing those who have been in power for a long time. Grassley said during an interview with Salem Radio host Hugh Hewitt Tuesday morning.
Amid accusations of sexual assault against a woman while in high school, the high school yearbook of Supreme Court nominee Brett Kavanaugh has prompted some questions. He questioned whether the hearing would take place if Ford declined to appear.
Sen. Thom Tillis, R-N.C., was asked if it was poor optics for an all-male panel of Judiciary Committee Republicans to be questioning Ford about her allegations (there are four women, all Democrats, also on the committee). Ford tells the Post that she sent a letter about Kavanaugh to Senator Dianne Feinstein via Eshoo's office.
Trump wasn't having that explanation, accusing the Democrats of obstruction. "We have a woman that has come forward, she deserves to be heard, it's important that her voice and story is shared and determinations will be made at that point".
Kavanaugh has denied the accusation. Grassley said on Tuesday that "the FBI is not doing any further investigation".
If the Judiciary committee's timetable slips, it would become increasingly hard for Republicans to schedule a vote before midterm elections on November 6 elections, when congressional control will be at stake.
Kavanaugh, 53, Trump's pick to replace the recently retired Justice Anthony Kennedy, has been vociferously resisted by Democrats, with liberal activists repeatedly disrupting the hearings.
Senator Susan Collins, a Maine Republican, told reporters she would like the chance to observe Dr Ford to decide the credibility of her account.
Sorting out the gap between Christine Blasey Ford's recollection of the events at a party more than 30 years ago and Judge Kavanaugh's flat rejection of her accusation would be tough in any circumstance.
