The head of the US military base in Greenland has been fired after she reportedly sent an email distancing herself from Vice-President JD Vance's criticism of Denmark.

The US military's Space Operations Command said Col Susannah Meyers had been removed from her role at Pituffik Space Base due to a "loss of confidence in her ability to lead".

Last month, Vance said Denmark had "not done a good job" for Greenlanders and had not spent enough on security while visiting the Danish territory.

The alleged email, released by a military news site, told staff Vance's comments were "not reflective" of the base. A Pentagon spokesman cited the article, saying "undermining" US leadership was not tolerated.

Following Vance's trip, on 31 March, Col Meyers is reported to have written: "I do not presume to understand current politics, but what I do know is the concerns of the US administration discussed by Vice-President Vance on Friday are not reflective of Pituffik Space Base."

Military.com - which published the email - said the contents had been confirmed as accurate to them by the US Space Force.

Appearing to confirm this was the reason for her firing, chief Pentagon spokesman Sean Parnell linked to the Military.com article in a post on X, writing: "Actions [that] undermine the chain of command or to subvert President [Donald] Trump's agenda will not be tolerated at the Department of Defense."
