A bipartisan, bicameral group lawmakers traveled to Denmark to reassure NATO ally amid President Donald Trump's push for the U.S. to acquire Greenland.

A bipartisan U.S. Congressional delegation's comments in Denmark contrasted with those emanating from the White House.

The US president says the UK, Denmark and other European countries will be charged a "10% tariff on any or all goods" exported to the US from 1 February.

President Donald Trump threatens steep tariffs on European nations unless Denmark sells Greenland to the U.S., citing national defense and security.

In a post on social media, Trump said a 10% tariff will take effect on Feb. 1, and will climb to 25% on June 1 if a deal is not in place for the United States to purchase Greenland.

Denmark's foreign minister said the closed-door meeting was a "frank but also constructive" discussion. He said a high-level working group would be formed "to explore if we can find a common way forward.

Seeking to calm tensions, Republicans and Democrats affirmed that they supported Denmark’s control of Greenland as President Trump vowed to buy it or take it over.

Yesterday, after Greenland’s prime minister, Jens-Frederik Nielsen, vowed to cast his lot with Denmark over the United States, Trump said that he didn’t “know anything about” Nielsen but that such a choice would be a “big problem for him.”
