Denmark’s prime minister, Mette Frederiksen, called the U.S.’s recent pressure on Greenland “unacceptable” Tuesday prior to a visit from second lady Usha Vance later this week.

"I have to say that it is unacceptable pressure being placed on Greenland and Denmark in this situation. And it is pressure that we will resist," said the prime minister, Reuters reported, to broadcasters from her country.

Vance’s office announced Monday that the second lady is going to Greenland on Thursday alongside her son and a U.S delegation. During her time in Greenland, Vance is going to “visit historical sites, learn about Greenlandic heritage, and attend the Avannaata Qimussersu, Greenland’s national dogsled race.”

“Ms. Vance and the delegation are excited to witness this monumental race and celebrate Greenlandic culture and unity,” the second lady’s office previously said.

Greenland’s prime minister, Múte Bourup Egede, criticized Vance and the delegation’s upcoming Greenland trip as being included in a “very aggressive” pressure campaign to take control of the autonomous Danish territory.

“Until recently, we could safely rely on the Americans, who were our allies and friends, and with whom we liked to work closely,” Egede said to a Greenlandic newspaper Sunday. “But that time is over, we have to admit that, because the new American leadership is completely and utterly indifferent to what we have stood together on so far, because now it is only a matter of them taking over our country over our heads.”

On Monday, President Trump went on defense over the decision to send Vance and the delegation to Greenland, saying that Danish officials invited them.

“This is friendliness, not provocation. We’re dealing with a lot of people from Greenland that would like to see something happen with respect to their being properly protected and properly taken care of. They’re calling us. We’re not calling them. And we were invited over there, and I thought it would be great,” Trump said amid a Cabinet meeting.

The Hill has reached out to the White House for comment.
