His post references a letter that was sent anonymously to US senator Dianne Feinstein earlier this year. The letter, which was later revealed to have been sent by California professor Christine Ford, claims that Kavanaugh assaulted her during a party in high school 30 years ago.
Ford alleged that as a high school student in suburban Maryland, just outside of Washington, a "stumbling drunk" Kavanaugh pinned her down, groped her and attempted to remove her clothing.
The allegations have plunged Kavanaugh’s extremely contentious nomination process into yet more uncertainty, with senior politicians and commentators demanding the allegations against him be investigated before senators decide whether he is fit to serve as a Supreme Court judge.
Judiciary Committee chairman Chuck Grassley has reportedly requested phone calls with Kavanaugh and his accuser before the confirmation vote.
Since he was announced as Trump’s nominee, pro-choice advocates have voiced concern that Kavanaugh will move to overturn Roe v Wade, the landmark Supreme Court ruling issued in 1973 that legalised abortion across the US.
