The critiques of the tax breaks come as new surveys released Wednesday found that the Senate Republican health-care bill is unpopular -- a Quinnipiac poll showed that just 16 percent of Americans support it, while a USA Today/Suffolk poll found the number even lower at 12 percent.
‘Larger Burden’
Corker, who faces re-election in 2018, voiced hesitation with tax cuts for the highest earners. Apart from the net investment income tax, the Republican bill repeals a 0.9 percent Medicare surtax on incomes above the same thresholds after 2022.
One prominent conservative, Mike Lee of Utah, has also expressed discomfort about the structure of the Senate bill.
He said in a statement Tuesday that the legislation "included hundreds of billions of dollars in tax cuts for the affluent, bailouts for insurance companies, and subsidies for lower-income Americans. But it ignored the middle-class families who have borne the brunt of Obamacare."
