President Donald Trump's declaration of a 15% global tax on imports would affect the trade deal they struck with Trump this summer as EU legislators hit pause on the deal's ratification until they get clarity.

Thousands of farmers driving tractors and waving flags descended Tuesday on the European parliament in Strasbourg in protest at a major trade deal signed with South America, ahead of a vote on whether to refer it to the courts.
