Donald Trump is setting up a prime-time media event to unveil his choice to fill the vacant seat on the United States Supreme Court.

Trump tweeted that he has made his selecion and will announce it at 8 p.m. ET Tuesday, presumably on live TV. He did not specify a network.

He has been trying to decide between Neil Gorsuch of the 10th Circuit Court of Appeals and Thomas Hardiman of the Third Circuit, according to media reports. His selection is expected to fill the seat previously held by the late Justice Antonin Scalia.
