WASHINGTON: President Donald Trump on Monday said he would not back down from his planned new tariffs on steel and aluminum imports, creating a possible standoff with top lawmakers from his own Republican party who have criticized the planned levies for threatening the US economy and possibly sparking a trade war. ?We´re not backing down,? Trump said during an Oval Office meeting with Israeli Prime Minister Benjamin Netanyahu. ?I don´t think you´re going to have a trade war.?
