He said he would have shared the letter with fellow Democrats on the Judiciary Committee while redacting identifying information and said Feinstein should have asked Kavanaugh about his character during hearings.
The FBI conducts background checks for federal nominees but the agency does not make judgments on the credibility or significance of allegations, according to a Justice Department statement Monday night.
The Supreme Court nominee has denied the allegations and said in a statement released Monday that he was prepared to "talk to the Senate Judiciary Committee in any way the Committee deems appropriate to refute this false allegation, from 36 years ago, and defend my integrity".
The official said the White House wants to avoid a public hearing on the allegations - a risky drama that could build sympathy for the accuser - but is willing to accept a confidential inquiry.
Senate Majority Leader Mitch McConnell, R-Ky., said Ford could testify privately or appear publicly before national television cameras.
Inside the White House, plans are not now being made in case Kavanaugh's confirmation unravels, including identifying a potential replacement nominee, according to a source familiar with the nomination process who spoke on condition of anonymity.
Said Sen. Orrin Hatch of Utah, a key Republican on the panel, said, "We should proceed as planned". We are talking about a lifetime appointment for Kavanaugh to the highest and most influential court in the country. "The hearing questions need to have a frame and the investigation is the best frame for that".
Asked about the situation several times during the day, Trump did not mention Ford's name but said he felt "terribly" for Kavanaugh, his wife "and for his lovely young daughters". Republicans are aiming for full Senate confirmation before the Supreme Court term begins October 1. He told reporters at the White House: "If it takes a little delay, it will take a little delay".
Ford detailed her allegation in a letter sent in July to Senator Dianne Feinstein, the committee's top Democrat.
In "Full Disclosure", Stormy Daniels Claims Trump Didn't Want to Be President
Life-ruining as that may be (or, rather, Mario Kart-ruining), it doesn't exactly make Stormy Daniels Susan B. Any time she had to look at Donald Trump on the TV screen, she thought to herself, "I had sex with that".
On today's Judiciary Committee, all 11 Republicans are men while four of the 10 Democrats are women.
Republican Sen. Susan Collins of ME, who has been wooed by Kavanaugh opponents hoping she'll vote with the Democrats, tweeted Tuesday she was "respectfully recommending" that at Monday's hearing the counsel for Ford be allowed to question Kavanaugh.
The development came after President Donald Trump showered sympathy on his embattled nominee and as Senate Republicans and Democrats fought determinedly over who should testify at a high-stakes hearing on the allegation just six weeks before major congressional elections. "I've said from the beginning that these are very serious allegations and she deserves to be heard".
Democrats complained that there was not a thorough FBI investigation of the allegations that took place, and no witnesses other than Hill and Thomas who were called.
"This is simply too distant and uncorroborated a story to warrant a new hearing or to delay a vote. More to the point, I never saw Brett act in the manner Dr. Ford describes".
"We still haven't heard from Dr. Ford, so do they want to have the hearing or not?"
Sen. Mazi Hirono (D-Hawaii) has said that she thinks Ford would feel victimized if she were forced to testify without a full report from the Federal Bureau of Investigation. He called Roe an "important precedent" during his Senate Judiciary confirmation hearing but refused to say whether the ruling was correct.
"I feel so badly for him that he's going through this, to be honest with you, I feel so badly for him", said Trump, who has himself faced numerous accusations of sexual harassment that he's denied.
While that's the biggest problem with the Wall Street Journal editorial on Ford and Kavanaugh, it's not the only one. The paper said the 2013 notes showed that Ford described a "rape attempt" in her late teens.
On trade - a day after imposing 10 percent tariffs on $200 billion worth of Chinese imports, to which China retaliated with $60 billion in additional tariffs on USA goods - Trump said "we've just started".
