There are sharp partisan splits on both questions, with about 8 in 10 Republicans calling it inappropriate for a White House official to act against the president.
According to Sunday reports, a dozen Republicans in blue states may vote against Tax Reform 2.0.
Prospects for the new tax legislation in the Senate are weak, given the slim Republican majority and concern over the potential for further blowing up the deficit with a new tax cut - without corresponding new revenue sources.
"Passage is not automatic", he added. The decline in unemployment and soaring gross domestic product, along with the tax overhaul Republicans argue is fueling the growth, have been obscured by the president's inflammatory moves on immigration, Vladimir Putin and other fronts, party leaders say.

America First Action, a political committee aligned with Trump, conducted a series of focus groups over the summer and concluded the party had a severe voter-turnout problem, brought on in part by contentment about the economy and a refusal by Republicans to believe that Democrats could actually win the midterm elections.
