Bernie Sanders will say he’s proud to carry the mantle of democratic socialism and will accuse President Trump of being a socialist when it comes to huge corporations and billionaires.

“While President Trump and his fellow oligarchs attack us for our support of democratic socialism, they don’t really oppose all forms of socialism,” Sanders will say later Wednesday at a speech at George Washington University, according to excerpts obtained by CNN.

“They may hate democratic socialism because it benefits working people, but they absolutely love corporate socialism that enriches Trump and other billionaires,” Sanders, a 2020 Democratic presidential candidate, will say.

Sanders is referring to Trump’s $1.5 trillion tax plan that slashed corporate taxes and reduced the rate for people earning more than $1 million a year.

The Vermont senator will defend democratic socialism as a continuation of the vision President Franklin Roosevelt advocated in his New Deal programs intended to restore prosperity to Americans after the Great Depression.

“We must recognize that in the 21st century, in the wealthiest country in the history of the world, economic rights are human rights,” the speech continues, according to CNN. “This is what I mean by democratic socialism.”

Sanders, who supports Medicare for all and free college tuition, said in an interview that he wants to encourage Americans who feel abandoned by the political process to speak up about their rights.

“What the political revolution means to me, above and beyond democratic socialism, is getting millions of people who have given up on the political process, working people and young people, to stand up and fight for their rights,” he told the Associated Press. “So those are the profound changes that we will be bringing about.”
