The president expressed sharp disapproval of NATO countries, indicating that America's financial commitment to support the alliance, particularly against Russia, is going to be under "very serious examination," Fox News reports.
"But I'm very disappointed in NATO," he said. "They weren't there for us. We pay trillions of dollars for NATO, and they weren't there for us."
While NATO countries are now stepping up to assist the U.S., Trump described the effort as too late.
"Now they want to come up, but there's no real threat anymore," he said.
