U.S., NATO alliance on the line as Trump set to meet with Rutte

Tensions are running high between President Donald Trump and NATO leaders, as grumblings grow over the U.S. withdrawing from the alliance.

NATO's relationship with the U.S. is being scrutinized by a growing number of Republicans, including Secretary of State Marco Rubio, who is questioning whether the U.S. still needs NATO.

Mark Rutte, NATO's secretary general, is reportedly scheduled to meet with Trump next week in Washington as the president puts more pressure on allied nations to do more to reopen the Strait of Hormuz as Operation Epic Fury steams on.
