President Donald Trump embarks Monday on the first major international trip of his second term – an opportunity to shore up relations with a trio of key Middle Eastern allies and prove his might as a dealmaker on the world stage.

President Trump has always viewed the presidency as a worldwide hunt for deals. And there is no better place for that than the Gulf, where a few men wield absolute authority over vast wealth.

President Donald Trump's administration is facing calls for an ethics probe amid plans to accept a $400-million "palace in the sky" jet from Qatar.

A deal on a plane that would become Air Force One has not been reached, but ethics experts say accepting it from Qatar would violate the Constitution’s emoluments clause.
