A second woman has come forward with allegations of sexual misconduct against President Donald Trump's US Supreme Court nominee Brett Kavanaugh.
Deborah Ramirez, a Yale university classmate of the judge, told the New Yorker that Mr Kavanaugh had exposed his genitals at a dormitory party.
The judge has denied both allegations, labelling the latest "a smear".
The make-up of the nine-judge Supreme Court is crucial, as it has the final say on often highly contentious laws.
Before Mr Kavanaugh can take up the vacant seat, he has to be approved by the 21-strong Senate Judiciary Committee and then the whole Senate.
Prof Christine Blasey Ford, who last week came forward alleging Mr Kavanaugh had sexually assaulted her in the early 1980s, has agreed to testify before the Senate committee on Thursday.
Senator Dianne Feinstein, the ranking Democrat on the committee, called for the "immediate postponement of any further proceedings" relating to Mr Kavanaugh's nomination in an letter sent to the committee's Republican chairman on Sunday evening.
What is the new allegation against Mr Kavanaugh?
Ms Ramirez alleges the incident occurred when she was a freshman at Yale University alongside Mr Kavanaugh during the 1983-4 academic year.
She says they were both taking part in a drinking game at a dormitory party where people sat in a circle and selected others to drink.
She says at one point, a plastic penis was pointed in her direction by one man, and later another exposed himself directly.
"I remember a penis being in front of my face," she said. "I knew that's not what I wanted, even in that state of mind."
Ms Ramirez said she was mocked and taunted when she remarked it wasn't real, and then ended up touching the genitals while attempting to push the man away.
