Mr Trump has cast doubt on the sexual assault allegations made against Mr Kavanaugh, tweeting on Friday: "I have no doubt that, if the attack on Dr Ford was as bad as she says, charges would have been immediately filed with local law enforcement authorities by either her or her loving parents".
"The framing at the moment is these two dichotomies of either completely exposing yourself to huge amounts of personal and professional risk, or saying nothing", she said. Other details over her appearance haven't been outlined and the back-and-forth was sure to continue on Sunday and into next week.
The new information came hours after the Senate committee agreed to a date and time for a hearing after almost a week of uncertainty over whether Ford would appear to tell her story. Chuck Grassley, R-Iowa, confirmed the meeting would be set at 10 a.m. Thursday. But Susan Collins - a Republican who sits on the Judiciary Committee - said she was "appalled" by Trump's tweet.
As a result, the committee postponed the vote on Justice Kavanaugh's nomination, previously scheduled for Monday. On Saturday, both sides convened for the phone call that lasted about 15-20 minutes.
Meanwhile, Republicans viewed Ford's requests as a way to delay voting on President Donald Trump's nominee.
Some of those details included whether Ford would testify to the committee before or after Kavanaugh; whether the committee would subpoena a possible witness to the alleged assault, Kavanaugh's boyhood friend Mark Judge; and who would conduct the questioning.
They noted that other witnesses are "essential for a fair hearing".
Both spoke on condition of anonymity because they were not authorised to discuss private conversations. They could also use staff attorneys to the Republican majority on the committee.
A search on OpenSecrets.org reveals Keyser's only political donation has been to former Democratic senator Byron Dorgan. The committee's 11 Republicans - all men - have been seeking an outside female attorney to interrogate Ford, mindful of the election-season impression that could be left by men trying to pick apart a woman's assertion of a sexual attack.
Keyser separately clarified to the Washington Post she believes Ford, but does not have any personal knowledge of the assault.
She pushed him away, touching his penis in the process, she said. They have protested the panel's treatment of Ford, comparing it to bullying. "Neither she nor her legal representative have contacted the chairman's office".
Smyth, Keyser, and Judge have denied Ford's allegation in letters to the committee under the penalty of felony perjury. "She should have her say".
Patience among Republicans, though, is running thin. Kavanaugh is the most unpopular Supreme Court nominee since 2005, according to NBC News polling - more unpopular than Harriet Miers, who was nominated by President George W. Bush but ultimately withdrew under criticism over her qualifications. He said he expected Kavanaugh to join the high court soon.
According to Grassley, the Senate Judiciary Committee is attempting to investigate Dr. Christine Blasey Ford and Deborah Ramirez's allegations, The Hill reported. Here are four reasons why Ramirez's accusations are even weaker than Christine Blasey Ford's.
Kavanaugh sent a statement to the New Yorker, denying the accusations.
