President Donald Trump is going down to the wire as he makes his choice on a replacement for retiring Supreme Court Justice Anthony Kennedy, but he says with his final four options "you can't go wrong."

Trump spoke to reporters Sunday afternoon before returning to Washington from a weekend at his private golf club in New Jersey, where he deliberated his decision amid furious lobbying and frenzied speculation. Relishing the suspense, Trump insisted he still hadn't locked down his decision, which he wants to keep under wraps until a 9 p.m. Monday announcement from the White House.

"I'm very close to making a final decision. And I believe this person will do a great job," Trump said. Asked by reporters how many people were being considered, the president said: "Let's say it's the four people ... they're excellent, every one."

While Trump didn't name the four, top contenders for the role have included federal appeals judges Brett Kavanaugh, Raymond Kethledge, Amy Coney Barrett and Thomas Hardiman. The White House has been preparing information materials on all four, who were part of a longer list of 25 names vetted by conservative groups.

Trump tweeted later Sunday that he was looking forward to the announcement and said an "exceptional person will be chosen!" He is hoping to replicate his successful announcement of Justice Neil Gorsuch last year.

The president has spent the days leading up to the decision mulling the pros and cons of the various options with aides and allies. He expressed renewed interest in Hardiman — the runner-up when Trump nominated Gorsuch, said two people with knowledge of his thinking who were not authorized to speak publicly. But the situation appeared to remain fluid.

Hardiman has a personal connection to the president, having served with Trump's sister on the 3rd U.S. Circuit Court of Appeals in Philadelphia. He also has a compelling personal story: He went to the University of Notre Dame as the first person in his family to go to college. He financed his law degree at the Georgetown University Law Center by driving a taxi.

Some conservatives have expressed concerns about Kavanaugh — a longtime judge and former clerk for Kennedy — questioning his commitment to social issues like abortion and noting his time serving under President George W. Bush as evidence he is a more establishment choice. But his supporters cite his experience and wide range of legal opinions. He is also former law clerk to Kennedy, as is Kethledge.
