WASHINGTON (AP) — Brett Kavanaugh and the woman accusing him of a decades-old sexual assault both indicated Monday that they would be willing to testify to a Senate panel as the confirmation of President Donald Trump's Supreme Court nominee shifted from seemingly painless to problematic.

Kavanaugh was seen arriving at the White House, with no immediate reason given, while all 10 Democrats on the Senate Judiciary Committee wrote the panel's Republican chairman asking him to postpone a scheduled Thursday vote on the nominee to give the FBI more time to investigate.

Democrats and some Republican senators have expressed concern over Christine Blasey Ford's private-turned-public accusation that a drunken Kavanaugh groped her and tried to take off her clothes at a party when both were teenagers at high schools in suburban Maryland.

Kavanaugh released a new statement calling the allegation "completely false" and saying he "had no idea who was making this accusation until she identified herself" on Sunday to The Washington Post.

"I am willing 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," Kavanaugh said.
