Exclusive-Aide to EU chief joins tariff negotiation team to spur US talks, sources say

BRUSSELS (Reuters) -The European Union has changed its team locked in trade talks with the Trump administration, bringing in a close aide to European Commission President Ursula von der Leyen to deal more swiftly with political questions arising from the technical negotiations, three sources familiar with the talks said. The move follows frequent outbursts of frustration by U.S. President Donald Trump at what the White House perceives as slow progress in talks with the EU. The move to bring more political decision-making to the EU team reflects challenges confronting the bloc as it negotiates a trading relationship with a U.S. president who has said repeatedly the EU was established to screw the United States.
