AKIPRESS.COM - Hundreds of protesters against US President Donald Trump's Supreme Court nominee Brett Kavanaugh have been arrested in Washington, DC, BBC reports.

Comedian Amy Schumer and model Emily Ratajkowski were among 302 people held for demonstrating against the nominee.

Republicans earlier declared an FBI report had exonerated him of sexual assault allegations.

But Democrats said the five-day inquiry was "incomplete" because it was limited by the White House.

The Senate will hold a procedural vote on the nominee on Friday.

The likelihood of Judge Kavanaugh winning a full Senate vote appeared to increase on Thursday after two Republicans whose backing will be essential gave a positive account of the FBI inquiry.

But the confirmation is not a certainty, with several senators undecided and one at risk of missing a vote because he is attending his daughter's wedding.

If confirmed to the lifetime position on America's highest court, the 53-year-old is expected to help conservatives dominate the nine-member panel, which has the final say on issues such as abortion, gun control and voting rules.
