President Trump said on Friday that he would host next year’s Group of 20 summit at the Trump National Doral golf club near Miami, ignoring the glaring ethical concerns that led him to drop a similar idea to host an economic summit at the property during his first term.

“Everybody wants it there,” Mr. Trump said to reporters, without elaborating who had called for such a thing. “It’s right next to the airport. It’s the best location. It’s beautiful.”

The plan would violate a criminal statute and ethics regulations that prohibit conflicts of interest for government employees — were it not for the fact that Mr. Trump is president. He is exempt from such rules, and the Supreme Court ruled last year that presidents have a broad but not fully defined criminal immunity for official acts taken while in office.

In 2019, Mr. Trump proposed but ultimately dropped a similar plan to host a Group of 7 meeting at the club in the face of overwhelming criticism — from Democrats and members of his own party — who said that he had crossed a line by merging foreign diplomacy with his personal business interests.

That criticism from Republicans did not immediately resurface on Friday, a sign of just how much Mr. Trump has worked to quash internal dissent and remake the G.O.P. in his image since his defeat in the 2020 election.

Mr. Trump, who had dismissed the criticism in 2019 as “irrational” hostility, insisted on Friday that he would make “no money,” and implied there would be no conflict of interest for him in hosting foreign leaders, their staff and security details at a property he owns. The White House said in a statement that the president’s resort would charge only “at cost” and not profit from the event. The White House said the same thing in 2019.
