The high-tax policy ideas of progressive Democratic presidential candidates Sens. Elizabeth Warren, D-Mass., and Bernie Sanders, I-Vt., run counter to what made America prosperous, according to Jesse Watters.

Watters rejected the two lawmakers' proposals to increase taxes on Tuesday on "The Five," claiming Warren's plan to target net worth was constitutionally tenuous.

In remarks to supporters in South Carolina, Warren touted her tax plan, claiming it will help all Americans have a better shot at success.

"When you make it so big that you are in the top one-tenth of one percent, pitch in two cents so everybody gets a chance to make it in this country," the Massachusetts lawmaker said.
