President Trump said early Monday that he will announce his choice for a Supreme Court nominee on Tuesday evening.
The president tweeted that the announcement will come 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.)," the president tweeted.
The president said last week he would announce his pick on Thursday, but is moving up the announcement.
Trump's shortlist to fill the late Justice Antonin Scalia's seat is said to include Judge William Pryor of Alabama, Judge Neil Gorsuch of Colorado and Judge Thomas Hardiman of Pennsylvania.
Republicans will need at least eight Democrats to support Trump's nominee to overcome the 60-vote filibuster hurdle.
Last week, the president met with Senate leaders ahead of the Supreme Court announcement.
Senate Minority Leader Charles Schumer (D-N.Y.) and Sen. Dianne Feinstein (D-Calif.) stressed after the meeting they want the president to pick a "mainstream" nominee to fill the high court's open ninth seat.
