President Trump promoted his platform for the NATO summit Tuesday morning, ahead of meeting with other defense partners.
He accused some countries of being behind on past payments.
Mr. Trump has repeatedly demanded that other member states pay a larger share to offset the amount America contributes.
The NATO summit is part of the president’s European tour. Relations between the U.S. and our allies in the European Union were strained by a trade war over steel and aluminum.
Like the collective defense group, Mr. Trump called the financial relationship between the U.S. and the EU as unfair for American workers.
Mr. Trump’s European tour will start with a stop in Brussels for the NATO summit. Thursday will have the president visiting London for a brief visit with Prime Minister Theresa May and Queen Elizabeth II. He will round out the trip by meeting with Russian President Vladimir Putin at the Helsinki summit.
