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 Supreme Court has been left with eight justices since February of last year after the death of Antonin Scalia. President Barack Obama put forward Merrick Garland to fill the vacany, but the nomination was blocked by Republicans who wanted to delay filling the vacancy until after the election.
