WASHINGTON (AP) — A top Danish official says a “fundamental disagreement” over Greenland remains with President Donald Trump after talks in Washington with Vice President JD Vance and Secretary of State Marco Rubio. The two sides did agree to create a working group to discuss ways to work through differences as Trump continues to call for a U.S. takeover of the Denmark’s Arctic territory of Greenland. Trump said before the talks that Greenland is essential for U.S. national security and he warned against Russian or Chinese influence. Meanwhile, Denmark announced plans to boost the country’s military presence in Arctic and North Atlantic.
