Asked whether she would like to see the same thing happen with French manufacturers Renault and PSA Peugeot Citroen, the National Front (FN) leader said: "He (Trump) is putting in place measures I have been demanding for years."
Speaking on France 2 Television, she described the policy as "economic patriotism, (and) intelligent protectionism."
"I don't mind explaining to French companies that they can not escape tax that they should be paying in France, that they cannot go offshore without suffering the consequences, A choice has to be made, a choice of patriotism."
