President Trump suggested Wednesday that NATO allies should increase their defense spending from 2 percent of their gross domestic product (GDP) to 4 percent.
"During the President’s remarks today at the NATO summit he suggested that countries not only meet their commitment of 2% of their GDP on defense spending, but that they increase it to 4%. The President raised this same issue when he was at NATO last year," White House press secretary Sarah Huckabee Sanders said in a statement.
"President Trump wants to see our allies share more of the burden and at a very minimum meet their already stated obligations," she added.
Bulgarian President Rumen Radev first told a national radio station that Trump had raised the prospect of a heightened spending commitment during a meeting with world leaders at the NATO summit.
