Vice President Vance toured a U.S. military base in Greenland on Friday and blasted Denmark for not investing enough in the territory.

March 28 (UPI) -- Vice President JD Vance and second lady Usha Vance are headed to Greenland Friday to visit a U.S. Space Force base.

US Vice-President JD Vance will join his wife Usha on a trip to Greenland later this week - a visit that comes after Donald Trump says he wants to take over the island.

Vice President JD Vance's visit to Greenland, Health Secretary Robert F. Kennedy Jr.'s push to ban synthetic dyes, and President Trump's executive order targeting the Smithsonian Institution are the key stories from the White House today.

Foreign policymakers worry that the vice president embodies a potentially permanent shift in the United States’ approach to European allies.

The United States military's northernmost base, Pituffik Space Base in Greenland, is a crucial cog in Washington's missile defences which US Vice President JD Vance will visit on Friday. The Pituffik base was used as a warning post for possible attacks from the Soviet Union during the Cold War and remains an essential part of the United States' missile defence infrastructure.
