Alex Bruesewitz, a top adviser for President-elect Donald Trump, remains in the hospital on Monday, where he’s suffered another fainting spell after tumbling over a lectern on stage Sunday night at a New York Young Republican gala, sources told The Post.

“He is still admitted to a hospital in New York where he has undergone a series of tests. Please keep this young fighter in your thoughts and prayers,” Bruesewitz’s lawyer Joseph D. McBride wrote on X Monday morning.

The 27-year-old Bruesewitz fainted again after being admitted to the hospital, according to two sources familiar with the incident. He had appeared totally fine before the incident at the gala.

The Trump adviser was mid-speech — energetically commending the New York Young Republican Club and giving shout-outs to prominent attendees — when he began slurring his words.

“I’m forgetting my words,” he managed to say before toppling forward over the lectern.

Raheem Kassam, a former senior aide to British politician Nigel Farage, came out on stage later to calm attendees’ nerves.

“I talked to our friend Alex Bruesewitz and you know what he said to me? He goes, ‘Did I at least look cool?’” Kassam said.

“I said, ‘Alex, you used gravity like I’ve seen nobody use gravity before in their lives,’” he joked. “But he’s recuperating back there, so give him a big cheer so he’ll hear you.”

Human Events editor Jack Posobiec said he spoke to Breusewitz backstage afterward and that he was OK.

“He is getting checked out by medical after having a brief fainting spell onstage. All levels are normal. Only thing he asked me was, ‘Did it look cool?’ He’ll be just fine,” Posobiec wrote on X, also speculating that it was a case of “dehydration + locked legs.”

Bruesewitz is CEO of X Strategies LLC, a political consultancy firm with a mission of “America First conservatism,” its website states, and he has authored several books on conservative politics.

The fainting spell notwithstanding, Bruesewitz — who travels the country giving pro-MAGA speeches — is no stranger to the podium.

“Bruesewitz has been the driving force behind the efforts to defeat Republicans who fight against Trump and the MAGA movement and works to replace them with Republicans who fight for values we hold dear,” an excerpt from his X Strategies, according to his bio.

Otherwise, spirits were high during the annual black-tie gala at Cipriani Wall Street, which sported a lineup of speakers that included former White House chief strategist Steve Bannon and senior Trump adviser Corey Lewandowski.
