Warner said he hopes conservatives in the Freedom Caucus in the House of Representatives will stick to their concerns about debt and the deficit.

“A quick sugar high with a tax cut that’s unpaid for when we’ve already got $19 trillion in debt is really unsustainable,” Warner said.

“Right now if interest rates go up 1 percentage point that adds $140 billion a year of additional spending right off the top just for debt service.”

The president-elect and Republicans in the House of Representatives want to lower taxes for individuals and businesses and collapse the current seven brackets into three.

Under Trump’s plan, for married joint filers who make less than $75,000 the tax rate would be 12 percent.

For married joint filers who make more than $75,000 but less than $225,000 the rate would be 25 percent.

For married joint filers who earn more than $225,000 the rate would be 33 percent.

Warner said Trump’s election was a broad rejection of the establishment.

“This was a rejection not just of the Democrats. It was a rejection of establishment Republicans. It was a rejection of the media. It was a rejection of corporate America,” he said.
