Sen Bernie Sanders’ contention that Joe Biden resoundingly won Super Tuesday because of the “corporate establishment,” is absurd, the former vice president said in an interview that aired Thursday.

“It’s ridiculous. Bernie. You got beaten by overwhelming support I have from the African-American community, Bernie. You got beaten because of suburban women, Bernie. You got beaten because of middle-class, hard-working folks out there, Bernie,” Biden said on NBC’s “Today” show.

Sanders, speaking on Wednesday after Biden won 10 of the 14 states that went to the polls on Tuesday, said Biden is backed by the “corporate establishment” and said “60 billionaires” have contributed funds to his campaign.

“Does anyone seriously believe that a president backed by the corporate world is going to bring about the changes in this country that working families and the middle class and lower-income people desperately need?” Sanders asked reporters.

Coming off a decisive win on Saturday in South Carolina and endorsements from former Democratic rivals Pete Buttigieg, Sen. Amy Klobuchar of Minnesota and former Rep. Beto O’Rourke, Biden pulled off a series of stunning wins on Tuesday, including taking Texas and Massachusetts.

Sanders won three states and is the projected winner in delegate-rich California.

Former New York Mayor Mike Bloomberg, who spent more than $550 million in a nationwide ad blitz, dropped out of the race on Wednesday after a poor performance and endorsed Biden.

In the “Today” interview, host Savannah Guthrie mentioned that President Trump and the Republicans have been touting the line that the system is rigged against Sanders getting the nomination at the convention this summer.

“Wonder why he’s saying that,” Biden said, adding that Trump would find Sanders, a democrat socialist, an easier opponent.

“I think the one thing the president doesn’t want to do from the very beginning is face me because I will beat him. Period. Period,” the former vice president said. “A rhetorical question: Have you ever, ever seen a sitting president get so involved in a Democratic primary and focus so much attention on not wanting a single person, me, from becoming president.”

He was also asked about Trump’s intention to pound the Democratic candidate on his dealings in Ukraine and his son’s involvement in the Ukrainian energy company Burisma.

“There’s nothing there, there. Donald Trump has corrupted the soul of this country. Donald Trump has pummeled the middle class … Donald Trump is a disaster and he knows it and he knows that I will be able to point it out. And I can hardly, hardly wait to debate him,” Biden said.

He also laughed off an ad released Wednesday by the Sanders’ campaign that shows former President Barack Obama singing the Vermont senator’s praises.

“It’s not at all a surprise. Everybody is embracing Barack. Barack was a great president, he’s a wonderful guy. He’s said a lot of nice things about a lot of people. But look the idea that Bernie Sanders was a great supporter of the president of United States and shares his views, I mean,” Biden said, chuckling. “C’mon. Anyway it doesn’t matter much.”

Asked about whether Obama would endorse the man who served at his side for two terms, Biden said he’s going to win the nomination on his own.

“Imagine had he endorsed me and we won as big as we did yesterday, you’d all be saying I won because of Barack. I’m winning because of me. I’m gonna earn this on my own,” he said.
