Exclusive: Brussels seeks to stall awarding of contract to firm fronted by US president’s lawyer in letter seen by Guardian

Brussels has clashed with Trump over trade, Ukraine and military spending, but the intervention in the Southern Interconnection pipeline project appears to mark the first time it has challenged a commercial venture by those close to the president.
