Brett Kavanaugh’s Supreme Court confirmation has been been roiled in recent days by Christine Blasey Ford’s allegation that he sexually assaulted her when they were teenagers at a party in the early 1980s.

Kavanaugh has vehemently and repeatedly denied the accusation.

Ford’s allegations have raised many questions — including about how and when they were made public. Republicans have pointed out that Democrats acted on the information just days before the Senate Judiciary Committee was slated to vote on Kavanaugh’s nomination. Democrats have stressed that Ford has spoken privately about her experience, years before Kavanaugh was nominated to the high court.

Here is what we know about the accusations, when those involved knew about them and how Washington is responding.
