From NYT article White House Proposes Slashing Tax Rates, Significantly Aiding Wealthy:

Democrats rejected what they described as magical thinking behind the plan and condemned it as a giveaway to the rich masquerading as a tax overhaul.

Senator Ron Wyden of Oregon, the ranking Democrat on the Finance Committee:

This is an unprincipled tax plan that will result in cuts for the 1 percent, conflicts for the president, crippling debt for America and crumbs for the working people. Instead of providing a real tax reform plan as promised, this administration is offering cakes to the fortunate few.
