President Donald Trump is scheduled to speak with four candidates for national security adviser on Sunday.

Army strategist Lt. Gen. H.R. McMaster, former United Nations Ambassador John Bolton, acting national security adviser Keith Kellogg and West Point superintendent Lt. Gen. Robert Caslen are all under consideration, press secretary Sean Spicer said, according to a pool report.


It is unclear whether Trump will speak to the candidates in person or over the phone. There are "potentially more" candidates, Spicer added. The president is spending the weekend at his Mar-a-Lago club in Florida.

Aboard Air Force One on his way to an evening rally in Melbourne, Florida, Trump told reporters, “I have many, many that want the job that want to be a part of it, I’ll make a decision in the couple of days, but we’re meeting with actually four of them tomorrow, all of whom want it."

He added, “I’ve been thinking about someone for the last three or four days; we’ll see what happens. I’m meeting with that person. They’re all good, they’re all great people.”

Former CIA Director David Petraeus, who Trump interviewed for secretary of state, is out of the running to fill the spot. Spicer did not have an update on whether retired Gen. Ray Odierno, a former Army chief of staff, was still under consideration.

Trump's first national security adviser, Michael Flynn, was ousted following revelations he lied to Vice President Mike Pence about the nature of conversations he held with the Russian ambassador. Trump's second pick, retired Vice Adm. Robert Harward, turned down an offer from the president to serve as his adviser earlier this week.
