Navarro, a White House adviser who believes foreign countries are stealing American jobs with cheap imports, had been marginalized within the West Wing by Kelly and Cohn. But with Kelly's diminished status and Trump looking to follow through on some of the trade threats he made during the campaign, Navarro and Ross provided him with a plan: Impose tariffs on steel and aluminum in the name of national security. Trump has also been keeping a close eye on the special election this month for a U.S. House seat in western Pennsylvania, which he considers the heart of his political base. In recent weeks, he has been told by associates that voters in places such as Pennsylvania's 18th District are looking for more to be done by the administration, according to two people familiar with the discussions, who spoke on the condition of anonymity to discuss private conversations.
