With primaries underway, conservative groups are stepping up their campaign against President Donald Trump’s controversial proposal to levy new steel and aluminum tariffs — warning that it could cause political peril for Republicans.
“We’re deeply concerned. We’ve made it clear to the administration that imposing tariffs is an enormous mistake,” said Tim Phillips, who runs Americans for Prosperity, a conservative group funded in part by billionaire brothers Charles and David Koch. “It will undercut their political chances in what’s going to be a challenging election year.”
