Trump tweeted Monday that he has "made my decision" and will announce it Tuesday at 8 p.m.
I have made my decision on who I will nominate for The United States Supreme Court. It will be announced live on Tuesday at 8:00 P.M. (W.H.)— Donald J. Trump (@realDonaldTrump) January 30, 2017
The court has been working with eight justices since the death last year of Justice Antonin Scalia.
President Barack Obama had nominated Merrick Garland for the post, but Senate Majority Leader Mitch McConnell refused to take up the nomination.
