"I have long heard that the most important decision a U.S. President can make is the selection of a Supreme Court Justice - Will be announced tonight at 9:00 P.M.," Trump tweeted on Monday morning.

Trump seems eager to reveal his pick, raising the subject on Sunday afternoon as well.

"Looking forward to announcing my final decision on the United States Supreme Court Justice at 9:00pmE tomorrow night at the @WhiteHouse," he tweeted. "An exceptional person will be chosen!"

The president also tweeted on Saturday: "Big decision will soon be made on our next Justice of the Supreme Court!"

All major broadcast and cable news networks plan to air Trump's announcement live. People without a television can stream the event online on C-SPAN or PBS NewsHour as embedded below.

Trump has not disclosed his top contenders to replace Justice Anthony Kennedy, who was a critical swing vote on the Supreme Court and late last month announced his decision to retire.

"I'm very close to making a final decision. And I believe this person will do a great job," Trump told reporters on Sunday afternoon after spending the weekend at his private golf club in New Jersey. "Let's say it's the four people … they're excellent, every one."

Though unconfirmed, the four judges up for consideration are believed to be Brett Kavanaugh, Raymond Kethledge, Amy Coney Barrett and Thomas Hardiman. White House officials have been prepping materials on those four, who have apparently been narrowed down from a list of 25 people that was screened by conservative groups.

Kavanaugh, who served as a clerk for Kennedy, has been praised for having a range of legal opinions but some conservatives worry about his commitment to abortion and other social issues.

Kethledge, another former clerk to Kennedy, is a judge on the U.S. Court of Appeals for the 6th Circuit in Cincinnati. Barrett has only served as a federal judge since last fall, raising concerns about her experience, but has been a Notre Dame Law School professor for many years. Hardiman, meanwhile, served with Trump's sister on the U.S. Circuit Court of Appeals for the 3rd Circuit in Philadelphia.

At a North Dakota campaign rally shortly after Kennedy announced his retirement, Trump indicated that he plans to choose a replacement who can sit on the court for decades to come.

"We have to pick a great one," he said. "We have to pick one that's going to be there for 40 years, 45 years."
