Carolyn Maloney, Jerry Nadler, and Dan Goldman were endorsed by the president.
Goldman said that Trump was attempting to meddle in the election.
If the endorsements are meant to sour Democratic voters on the candidates, they're similar to attempts by Democrats to meddle in the Republican primaries.
Donald Trump praised Democrats he has previously criticized and even endorsed the lawyer who led his first impeachment in a series of posts on Truth Social.
The seemingly sarcastic endorsements came as Trump continues to wield his power over the Republican party.
Dan Goldman was endorsed by Trump in the first post. Goldman was the top Democrat in the House.
He was honorable, fair, and highly intelligent, and that's why I did this. The Senate did not convict Trump in either of the impeachment cases.
"While it was my honor to beat him, and beat him badly, Dan Goldman has a wonderful future ahead," Trump said. Winning against him made me realize how good I am.
Goldman was quick to respond to the endorsement.
Donald Trump attacked Dan Goldman. He is pretending to support Goldman. Goldman said that Trump is attempting to meddle in the election. It's clear that only one candidate in NY 10 is living rent-free in Trump's head, and this is a pathetic attempt at fooling Democrats who are far smarter than Trump is.
The two Democrats who are running against each other for the House because of redrawn congressional districts in New York City were praised by Trump.
Trump said he was endorsing a candidate.
"She is a kind and wonderful person, who has always said terrific things about me, and will support me no matter what I do," Trump wrote.
Jerry Nadler is a hard driving man with an attention to detail that is unlike anyone else in congress. Trump said that Nadler was high energy, quick-witted, and bright.
You can't go wrong with either one, but Carolyn is the better man. She is going to lead our country into a prosperous and green future. He said that Carolyn has his complete and total endorsement.
The endorsement was rejected by the author.
I don't accept any endorsement from Donald Trump. Trump is not respectful of women. She wrote that he claimed that the 2020 election was a lie. The chair of the Oversight Committee is investigating the storage of his classified documents at Mar-a-Lago.
The representatives for Trump and Nadler did not respond to the requests for comment.
It's possible that the endorsements are meant to sour Democratic voters on the candidates.
Democrats have funded ads that promote far-right candidates who they think will be easier to beat in the general elections, a move that has been criticized as risky.
Business Insider has an article on it.
