In the event that congresspersons don’t change their voting goals, Judge Kavanaugh will be designated to the best US court.
The vote is normal at around 17:00 nearby time (21:00 GMT).
Mr Kavanaugh has been involved in a severe fight to fight off rape claims.
What’s going on in the Senate?
It’s really been in session for the duration of the night covering the issue, in spite of the fact that the discussion has occurred in a to a great extent void chamber.
Congresspersons are required to be there in power from 15:30 in the number one spot up to the vote.
The Senate is part 51-49 for the Republicans and the vote will be to a great extent along partisan principals. Mr Kavanaugh would in reality just need a 50-50 vote, as that would compel a sudden death round to support him from VP Mike Pence.
So what are the numbers?
The count in a procedural vote on Friday was 51-49.
It’s looking as if there will be a comparative two-vote edge in Saturday’s vote, excepting a minute ago changes of psyche.
That is on account of Republican legislators who had been faltering on the issue have caught, one special case, on Mr Kavanaugh’s side.
The one special case is Gold country Representative Lisa Murkowski. In spite of the fact that she said Mr Kavanaugh was a “decent man”, she said he was “not the ideal individual for the court right now” and his “appearance of inappropriateness has turned out to be unavoidable”. She remains a no.
In any case, Democrat Joe Manchin told the Senate on Friday he would vote yes. He is confronting a troublesome re-race crusade in West Virginia, a customarily Republican express that Mr Trump won by a surprising margin.
He said he “observed Judge Kavanaugh to be a qualified legal adviser”, yet later confronted yells of “disgrace” from nonconformists.
