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 uniiversity of the judge, detailed the alleged incident to the New Yorker.

She alleges Mr Kavanaugh exposed his genitals at a dormitory party and thrust them in her face, causing physical contact without consent.

The judge has denied both allegations, labelling the latest “a smear”.

Professor Christine Blasey Ford, who last week came forward as the woman alleging Mr Kavanaugh sexually assaulted her in 1982, has agreed to testify about the allegation at a Senate Judiciary Committee hearing 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.

The confirmation of any new justice for the Supreme Court is pivotal, as the nine-judge court gives the final word on highly contentious laws with an immense impact on US public life.
