“There needs to be a profound change in the way the Democratic Party does business. It is not good enough to have a liberal elite,” Sanders said Monday on CBS's "This Morning."

“I come from the white working class, and I am deeply humiliated that the Democratic Party can’t talk to the people where I came from."

Sanders said it was the failure to win over working-class voters and not FBI Director James Comey's email investigation that was largely to blame for Hillary ClintonHillary Diane Rodham ClintonNSA leaker Reality Winner released from federal prison Monica Lewinsky signs production deal with 20th TV Police investigating death of TV anchor who uncovered Clinton tarmac meeting as suicide MORE's loss to Donald TrumpDonald TrumpDOJ asks Supreme Court to revive Boston Marathon bomber death sentence, in break with Biden vow Biden looking to build momentum for Putin meeting DOJ tells media execs that reporters were not targets of investigations MORE

"She should have won this election by 10 percentage points. The question is: Why is it that millions of white working class people who voted for [President] Obama turned their backs on the Democratic Party?" he said.

Moving forward, Sanders said Americans should re-evaluate the Electoral College, adding "a campaign for president should not be in 15 states." He also said he would fight to ensure that Trump develops policies that help the working class.

"We will hold Mr. Trump accountable. We have all of the things he has said, and we are going to say to Mr. Trump if you have the courage to actually stand up to the big money and trust of the billionaire class, if you have the courage, in fact, to develop policies to improve lives for working people, count us in," Sanders added. "You want for increase the infrastructure and pay equity for women? We are on your side."

Later in the interview, when asked if he would have won the election against Trump, Sanders responded "maybe, maybe not." He said it's too soon to say whether he will run for president again in 2020.

Sanders mounted a strong challenge to Clinton in the Democratic primaries, beating her in several of the Midwestern states, like Michigan and Wisconsin, that ultimately decided the election by going to Trump.
