Lokke Rasmussen is the latest wary European ally to visit the White House since Trump took office, looking to ease concerns that the new administration will honor multilateral agreements with Europe and take a firmer stance against Russian aggression.
The two leaders will hold bilateral talks at the White House today.
Since taking office, Trump has vowed to uphold the longstanding NATO military alliance. But he recently declared that Germany owes "vast sums of money" to NATO and the US "must be paid more" for providing defense.
