Spokesman Taylor Foy said the panel is looking into it.
Ms Ramirez recalled that Mr Kavanaugh exposed himself at a drunken dormitory party, thrust his penis in her face, and caused her to touch it without her consent as she pushed him away, the magazine reported. Ford said Kavanaugh sexually assaulted her at a high school party 36 years ago, pinning her down and trying to take off her clothes, when she was 15 and he was 17.
But the lawyers say the Republican-controlled Senate panel hasn't said who will be asking questions of Ford and Kavanaugh. A White House spokeswoman added in a second statement that the allegation was "designed to tear down a good man".
Throughout the week, the committee reached out to several people who might have information about a house party in 1982 where Ford, a 51-year-old college professor, says she was sexually assaulted by Kavanaugh, a source with knowledge of the investigation told USA TODAY, adding several people have offered statements to the committee.
Senator Lindsey Graham of SC, a senior member of the Judiciary Committee, said on "Fox News Sunday" said he wouldn't vote against Kavanaugh without additional evidence."Unless there's something more, no, I'm not going to ruin Judge Kavanaugh's life over this", he said.
The White House is approaching Ms Ford's potential testimony with trepidation, nervous that an emotional performance might not just damage Mr Kavanaugh's chances but could further energise female voters to turn out against Republicans in November.
A senior White House adviser meanwhile also suggested the allegations were political.
One of Trump's defenses of Kavanaugh was his 'top of the line education'.
Ramirez was initially hesitant to speak publicly, she told the magazine, partly because her memory contained gaps because she had been drinking at the time of the alleged incident.

Law professor Aviva Orenstein told Reuters that #MeToo "may have influenced the judge's willingness to allow more witnesses". However, he was released on $1 million bail with strict conditions that he remains at home till his sentencing.
Reports say her lawyers - Debra Katz, Lisa Banks and Michael Bromwich - agree Ford will go first, to be followed by Kavanaugh.
However, one former classmate remembered hearing about the incident from another, and independently corroborated numerous details offered by Ms Ramirez. The magazine said numerous people they contacted did not respond to interview requests, others declined to comment or said they did not attend or remember the party.
The judge has denied both allegations, labelling the latest "a smear". The terms of their agreement provide that Kavanaugh will also appear before the committee, but he will not be in the room while Ford is speaking or being questioned.
"I would think an FBI investigation would be warranted", she told The New Yorker. Countless people from every phase of Brett Kavanaugh's life have testified that he is a good man of the highest character and integrity.
But, even though Feinstein said she kept quiet, details of the allegation began to leak.
White House spokesperson Kerri Kupec said of those who allegedly attended the party, "One week ago, Dr. Christine Ford claimed she was assaulted at a house party attended by four others".
Kavanaugh has adamantly denied the allegations leveled by Ford. "Neither she nor her legal representative have contacted the chairman's office", the statement reads.
Christine Blasey Ford agreed to give her testimony Thursday after an increasingly ugly weeklong standoff that saw her forced to leave her California home as she faced death threats and the president openly attacked her credibility. The accusations from Christine Blasey Ford, denied vehemently by Kavanaugh, threaten to slow his Senate confirmation vote, with Democrats saying the FBI should investigate the charges, a demand that is not gaining traction among Republicans. "As you know, we've never been in communication with you or your client".
