If that happens, Senate Democrats could stop any Trump nominee to the high court for the rest of his term, leaving the Supreme Court with just eight justices and prone to deadlocks in crucial rulings.
A lawyer who's close to the White House told Politico the president is not considering withdrawing Kavanaugh's nomination. "That was true when he was in high school, and it has remained true to this day", the letter states.
It's also a significant challenge for Republicans who are struggling to win suburban women's votes in the November 6 election that will decide control of both houses of Congress.
The South Carolina senator says if the panel is going to hear from Ford, "it should be done immediately" so the confirmation process can continue as scheduled.
"It raises a lot of questions about Democrats' tactics and motives to bring this to the rest of the committee's attention only now rather than during these many steps along the way", Grassley's statement reads. Watching is wife Ashley, with daughters Margaret, second from left, and Eliza. As of late last week, Kavanaugh was expected to proceed on a party-line vote to a full Senate floor consideration.

One of those women, former Apprentice contestant Summer Zervos, is now suing Trump for defamation over his claim she lied about his alleged assault on her.
Democrats surely were hoping the letter would prompt a federal inquiry and stall Kavanaugh's confirmation until after the midterm elections, when they hope to take over the Senate. The Post said it had reviewed the therapist's notes, which were provided by Ford. Ford says four boys were at the party, but only two boys were in the room at the time.
Ford said she remembers that it was in Montgomery County, not far from the country club, and that no parents were home at the time.

"For too long, when women have made serious allegations of abuse, they have been ignored", Schumer said.
Senate Judiciary Chairman Chuck Grassley, R-Iowa, released a letter on Friday signed by 65 women who said they knew Kavanaugh in high school and defended his character.
"These are all the ills that I was trying to avoid", Ford told the Post, explaining her decision to come forward. Asked if that included testimony under oath at a public hearing before senators, Katz told the CBS "This Morning" program: "She's willing to do what she needs to do".
