Copenhagen. US President Donald Trump suggested Friday that he may punish countries with tariffs if they don’t back the United States controlling Greenland, a message that came as a bipartisan Congressional delegation sought to lower tensions in the Danish capital.

Trump for months has insisted that the US should control Greenland, a semiautonomous territory of NATO ally Denmark, and said earlier this week that anything less than the Arctic island being in US hands would be “unacceptable.”

During an unrelated event at the White House about rural health care, he recounted Friday how he had threatened European allies with tariffs on pharmaceuticals.

“I may do that for Greenland too,” Trump said. “I may put a tariff on countries if they don’t go along with Greenland, because we need Greenland for national security. So I may do that,” he said.

He had not previously mentioned using tariffs to try to force the issue.

Earlier this week, the foreign ministers of Denmark and Greenland met in Washington this week with US Vice President JD Vance and Secretary of State Marco Rubio.

That encounter didn’t resolve the deep differences, but did produce an agreement to set up a working group — on whose purpose Denmark and the White House then offered sharply diverging public views.

European leaders have insisted that is only for Denmark and Greenland to decide on matters concerning the territory, and Denmark said this week that it was increasing its military presence in Greenland in cooperation with allies.

A Relationship that ‘We Need to Nurture’
In Copenhagen, a group of US senators and members of the House of Representatives met Friday with Danish and Greenlandic lawmakers, and with leaders including Danish Prime Minister Mette Frederiksen.

Delegation leader Senator Chris Coons, a Delaware Democrat, thanked the group’s hosts for “225 years of being a good and trusted ally and partner” and said that “we had a strong and robust dialogue about how we extend that into the future.”

Senator Lisa Murkowski, an Alaska Republican, said after meeting lawmakers that the visit reflected a strong relationship over decades and “it is one that we need to nurture.” She told reporters that “Greenland needs to be viewed as our ally, not as an asset, and I think that’s what you’re hearing with this delegation.”

The tone contrasted with that emanating from the White House. Trump has sought to justify his calls for a US takeover by repeatedly claiming that China and Russia have their own designs on Greenland, which holds vast untapped reserves of critical minerals. The White House hasn’t ruled out taking the territory by force.

“We have heard so many lies, to be honest and so much exaggeration on the threats towards Greenland,” said Aaja Chemnitz, a Greenlandic politician and member of the Danish parliament who took part in Friday’s meetings. “And mostly, I would say the threats that we’re seeing right now is from the US side.”

Murkowski emphasized the role of Congress in spending and in conveying messages from constituents.

“I think it is important to underscore that when you ask the American people whether or not they think it is a good idea for the United States to acquire Greenland, the vast majority, some 75%, will say, we do not think that that is a good idea,” she said.

Along with Sen. Jeanne Shaheen, a New Hampshire Democrat, Murkowski has introduced bipartisan legislation that would prohibit the use of US Defense or State Department funds to annex or take control of Greenland or the sovereign territory of any NATO member state without that ally’s consent or authorization from the North Atlantic Council.

Inuit Council Criticizes White House Statements
The dispute is looming large in the lives of Greenlanders. Greenland’s prime minister, Jens-Frederik Nielsen, said on Tuesday that “if we have to choose between the United States and Denmark here and now, we choose Denmark. We choose NATO. We choose the Kingdom of Denmark. We choose the EU.”

The chair of the Nuuk, Greenland-based Inuit Circumpolar Council, which represents around 180,000 Inuit from Alaska, Canada, Greenland, and Russia’s Chukotka region on international issues, said persistent statements from the White House that the US must own Greenland offer “a clear picture of how the US administration views the people of Greenland, how the US administration views Indigenous peoples, and peoples that are few in numbers.”
