Overhauling the American tax system was a key goal of the Republican government when Trump won the White House and the GOP held both chambers of Congress a year ago.
The dinner date comes after the president stunned GOP congressional leaders by striking a deal last week with the two senior Democrats for a short-term spending and debt-ceiling deal.
Said Adam Brandon, president of FreedomWorks, "Talk about burning bridges with the grass roots".
"I think it's perfectly fine", Cruz said. As North Dakota's former tax commissioner, I understand how much these issues directly impact North Dakota families, farmers, and workers - which is why any tax reform plan must be done with their best interest in mind.
Trump said a tax reform plan is being drafted that would focus on the middle class and that "the rich will not be gaining at all with this plan".
Trump is set to host Senate Minority Leader Chuck Schumer (D., N.Y.) and House Minority Leader Nancy Pelosi (D., Calif.) on Wednesday night for a meeting that may include discussion of his new bipartisan tax goals.
Senate Majority Leader Mitch McConnell and GOP committee members are meeting Tuesday with President Donald Trump's top economic adviser, Gary Cohn, and Treasury Secretary Steven Mnuchin.
Trump rescinded that order, saying it exceeded presidential powers, but has given Congress six months to come up with a legislative replacement.
Trump has said he's simply doing "what the people of the United States want to see".
"We haven't changed this tax code for many, many, many, years, before we even had cell phones".
Rank-and-file Democratic lawmakers who were at the Capitol Tuesday expected that they would receive a draft document by at least Wednesday.
"I think it's really - the whole concept of what we're trying to do is very, very important", he continued.
One thing President Trump knows, as do many mainstream Americans, is that most of America who lives and works outside of the D.C. Beltway is fed up with partisan politics.
66 percent of voters said it was good for the country for Trump to work with congressional Democrats. If Republicans can't produce results with control of both houses, Trump will involve Democrats in the mix.
