Democratic presidential candidate Bernie Sanders says he supports raising the top marginal tax rate to “over 50 percent” – and increasing the corporate tax rate.

In an interview Thursday on PBS’ Charlie Rose program, the Vermont senator, who is campaigning unabashedly on a platform of “redistribution of wealth” from the nation’s highest earners to the “disappearing” middle class, revealed that he appears to be gaining traction with his ideas. Sanders said he’s raised more than $6 million in small donations for his campaign and expects to cross the $10 million mark by June 30.

Sanders said he is “working right now on a comprehensive tax package, which I suspect will, for the top marginal rates, go over 50 percent,” though he wouldn’t endorse a specific rate yet.

And Sanders said he wants to raise the corporate tax rate, as well as eliminate loopholes that allow corporate and wealthy taxpayers to reduce their tax bill.
