“We have so much in common with the Trump administration, it wouldn’t make sense to have a separate tax bill from Secretary Mnuchin, a separate one from Gary Cohn,<br />a third from whomever,” Mr. Brady said on Fox News, referring to the Treasury secretary, Steven T. Mnuchin, and to one of Mr. Trump’s top economic advisers.<br />However, facing a backlash from retailers, energy companies and conservative think tanks<br />that warn that consumer prices will soar under the House Republican plan, Mr. Trump and Mr. Mnuchin have sounded cool to the idea.<br />Mr. Trump is under added pressure not to again fail supporters who he promised would “get sick of all the winning.”<br />“They need to cut taxes, cut spending, and build the wall,” said Judson Phillips, the founder of the conservative group Tea Party Nation.<br />“If they will do that, the base will be forever in love with them.” He said he did<br />not want Mr. Trump to get bogged down in Mr. Ryan’s complicated tax agenda.
