WASHINGTON — Donald Trump, now acquitted in his second Senate impeachment trial, is preparing for the next phase of his post-presidency life. He is expected to reemerge from a self-imposed hibernation at Mar-a-Lago in Florida, and is eyeing ways to reassert his power.

But after being barred from Twitter, the former president lacks the social media bullhorn that fueled his political rise. And he’s confronting a Republican Party deeply divided over the legacy of his jarring final days in office. Searing video images of the day played on loop during his impeachment trial, which ended Saturday.

Trump remains popular among the GOP base, but many Republicans in Washington have cooled to him.

Friends and allies expect Trump to resume friendly media interviews after weeks of silence. He has met with political aides to discuss efforts to help Republicans try to take control of the House and Senate in the 2022 midterms elections.

“I imagine you’ll probably be hearing a lot more from him in the coming days,” senior adviser Jason Miller said.

In a statement after the vote, Trump offered few clues, but was defiant as he told supporters their movement “has only just begun.

“In the months ahead I have much to share with you, and I look forward to continuing our incredible journey together to achieve American greatness for all of our people,” he said.

Sen. Lindsey Graham, who spoke with Trump on Saturday night, acknowledged that Trump is “mad at some folks,” but also “ready to move on and rebuild the Republican Party” and “excited about 2022.”

In their conversations, Graham has stressed to Trump, who has threatened to start his own party to punish disloyal Republicans, that the GOP needs him to win.

“I said, ‘Mr. President, this MAGA movement needs to continue. We need to unite the party. Trump-plus is the way back in 2022,”’ Graham, R-S.C., told “Fox News Sunday.”

“My goal is to win in 2022 to stop the most radical agenda I’ve seen coming out of the Democratic presidency of Joe Biden. We can’t do that without Donald Trump, so he’s ready to hit the trail and I’m ready to work with him,” Graham said.

Graham said Senate Republican leader Mitch McConnell, who voted to acquit but then delivered a scalding denunciation of Trump, “got a load off a chest, obviously.”

Graham said later in the interview: “If you want to get something off your chest, fine, but I’m into winning.”

At his Palm Beach club on Saturday night, Trump was in a joyous mood as he enjoyed dinner on a patio packed with people. After a mellow last several weeks, one member described a party atmosphere not felt since before the election.

Still, Trump isn’t in the clear yet. No longer protected by a Justice Department opinion against the prosecution of sitting presidents, he now faces multiple ongoing criminal investigations.

“He didn’t get away with anything — yet,” McConnell, R-Ky., after the vote. “We have a criminal justice system in this country. We have civil litigation. And former presidents are not immune from being accountable by either one.”

McConnell voted to acquit Trump on the grounds the trial was unconstitutional because he is no longer in office, but insisted, “There’s no question — none — that President Trump is practically and morally responsible for provoking the events of the day.”
