U.S. Secretary of State Marco Rubio told NATO allies on Thursday that Washington remained committed to the alliance but expected them to spend far more on defence and would give them some time to do so.

BRUSSELS (AP) — European NATO allies and Canada on Friday said they are willing to ramp up defense spending but are cool on American demands for the size of their military budgets, particularly given U.S. President Donald Trump’s readiness to draw closer to Russian leader Vladimir Putin.

Marco Rubio is visiting NATO's headquarters for a meeting of foreign ministers, putting him on the front lines of the Trump administration's push against U.S. allies.
