President Trump heads to Missouri Wednesday to give a sales pitch for tax reform, an effort which the administration hopes could put the president back on message.

The Hill reports that the speech will carry a populist tone, providing few policy details:

“The president is going to lay out his vision to bring back Main Street by reducing the crushing tax burden on our companies and our workers and also to restore our competitive advantage by repairing and reforming our badly broken tax code,” a senior White House official told reporters Tuesday.

Administration officials said that Trump will talk about how middle-class tax cuts will result in American workers seeing bigger paychecks and how he plans to “un-rig” the economy and eliminate benefits for special interests.

Success on the tax bill would mark the administration’s first major legislative win, and could help restore some measure of public confidence in a beleaguered Republican Congress with brutally low approval ratings.

The effort is also a test of whether Trump can mend his relationship with fellow party members he has antagonized of late:

While Senate Republicans are committed to overhauling the tax code, “there’s some frustration that we’re doing it with some headwinds that aren’t necessary,” Toomey added.

Supporters of tax reform say that Wednesday’s speech gives Trump an opportunity to discuss an issue that unites Republicans and the business community.

“This allows him to connect with the American people on an issue that most Americans get,” said Grover Norquist, president of Americans for Tax Reform.
