Tax reform the next big ticket item on Trump's legislative agenda

After failing to agree on a replacement to Obamacare, the GOP turns to taxes.

“ObamaCare will explode and we will all get together and piece together a great healthcare plan for THE PEOPLE. Do not worry!” Trump tweeted.

Vice President Mike Pence issued a similar response during a speech in Charleston, West Virginia, a state where Trump was very popular in the 2016 election but that has a population that is heavily dependent on Medicaid for health care coverage.

"We will end the Obamacare nightmare and give the American people the world class healthcare they deserve," Pence said.

"Now we're going to move on with the rest of our agenda because we have big ambitious plans to improve people's lives in this country," Ryan said. "We want to secure the border. We want to rebuild our military. We want to get the deficit under control. We want infrastructure and we want tax reform."

In the Oval Office on Friday, Trump told reporters passing tax reform is his first legislative goal.

"I would say that we will probably start going very, very strongly for the big tax cuts and tax reform. That will be next," he said.

At an event hosted by Axios, Treasury Secretary Steve Mnuchin said the administration thinks tax reform is possible by the August recess.

"We’re going to do tax reform as absolute," Mnuchin said. "We are reforming both personal and the corporate side."

But overhauling the nation's complicated tax code by the end of the year is an ambitious goal.
