Former President Donald Trump will imminently announce his plans to run for president in 2024, and it will be a "professional, very buttoned-up announcement," his longtime advisor Jason Miller said Friday.

Trump has been teasing a "big announcement" due to take place at Mar-a-Lago on November 15, which is widely expected to be about his 2024 candidacy.

"President Trump is going to announce on Tuesday that he's running for president, and it's going to be a very professional, very buttoned-up announcement," Miller told Steve Bannon on his "War Room" podcast.

Miller said that he had done a "run-through" with Trump's logistics team, and they were "ready to go."

The former Trump aide and CEO of right-wing social media platform Gettr added that he had spoken to the former president on the golf course that morning about his announcement plans.

"Look, there doesn't need to be any question. Of course, I'm running," Miller said Trump told him. "I'm going to do this, and I want to make sure that people know that I'm fired up, and we gotta get the country back on track."

Trump has long been hinting at his plans to run in 2024, which would be his third presidential run.

However, the former president has experienced an unexpected setback following the GOP's lackluster midterm results, for which many in the party have directly blamed Trump.

Many Trump-endorsed candidates in competitive races lost or underperformed, and an expected Republican "red wave" failed to materialize.

Miller's comments to Bannon marked a change in tone from earlier this week when he told Newsmax he was advising Trump to hold off until after the Georgia Senate run-off in December.

While reports suggest many around Trump are urging him to delay his 2024 announcement until after the Georgia race, he appears determined to stick to his schedule, based on comments from those close to him and his campaign's emails to supporters.

The disappointing midterm results have also led to some Republicans and media figures suggesting his political rival, Florida Gov. Ron DeSantis, would be a better candidate in 2024.

In recent days Trump has been lashing out at DeSantis, who he has nicknamed Ron DeSanctimonious, and suggested he is disloyal for not ruling out a 2024 run.

The former president is reportedly furious about the midterm results behind closed doors and is becoming increasingly isolated as members of his inner circle grow tired of his ranting.
