United States President Donald Trump defended plans to receive a new Air Force One as a gift, after reports he will accept a luxury Boeing jet from Qatar despite strict rules on presents for US presidents.

Calling the plane a “flying palace,” ABC News, which first reported the story, said the Boeing 747-8 jumbo jet gifted from the Qatari royal family would possibly be the most expensive gift ever received by the American government.

The controversy around the jet — and Trump’s boast that it was coming “free of charge” — builds on questions the US leader is facing over potential conflicts of interest with his family businesses and use of public office.

In a social media post late Sunday that made no mention of Qatar, Trump went on the offensive to claim the plane was a temporary “gift” that would go to the Defense Department, and would replace an existing four-decade-old model.

Trump, 78, said the process was unfolding as a “transparent transaction” but did not specify whether any party was receiving something in return, and instead blamed Democrats for wanting to cash out on a new Air Force One unnecessarily.

Qatar swiftly sought to downplay the uproar, saying reports describing the jet as a gift “are inaccurate.”

“The possible transfer of an aircraft for temporary use as Air Force One is currently under consideration between Qatar’s Ministry of Defense and the US Department of Defense,” said Ali Al-Ansari, Qatar’s media attache to Washington, stressing that no decision had been made.

The US Constitution prohibits government officials from accepting gifts “from any King, Prince or foreign State,” in a section known as the emoluments clause.

But Trump would skirt the law by handing the jet to his presidential library after he leaves office.

The plan is to be announced as Trump travels to three Middle East countries this week, including Qatar, reported ABC and The New York Times.

Acceptance of the gift has raised ethical questions from both sides of the political aisle as it appears to flout laws set up to stanch government corruption.

Laura Loomer, a far-right ally of Trump, said accepting Qatar’s plane would be a “stain” on the administration.

“We cannot accept a $400 million ‘gift’ from jihadists in suits,” she posted on X. “The Qataris fund the same Iranian proxies in Hamas and Hezbollah who have murdered US Service Members.”
