WASHINGTON (AP) -- Aiming to put his mark on the world map, President Donald Trump has talked to aides and allies about buying Greenland for the U.S.

A Trump ally told The Associated Press on Thursday that the president had discussed the purchase but was not serious about it. The ally spoke on condition of anonymity to discuss private conversations.

Still, it wouldn't be the first time an American leader tried to buy the world's largest island, an autonomous territory of Denmark.

In 1946, the U.S. proposed to pay Denmark $100 million to buy Greenland after flirting with the idea of swapping land in Alaska for strategic parts of the Arctic island.

Neither the White House nor Denmark immediately commented Thursday.

Rep. Mike Gallagher (R-Green Bay) expressed support for the plan in a tweet Thursday night, saying, "The United States has a compelling strategic interest in Greenland, and this should absoutely be on the table."

The story was first reported by The Wall Street Journal.
