Democratic presidential candidate Bernie Sanders cranked up his fight with party leaders on Sunday, backing a challenger to the Democratic National Committee's chairwoman and accusing the party's establishment of trying to anoint Hillary Clinton as the nominee for president.
In a series of television interviews, Sanders remained defiant despite what he acknowledged was an uphill fight to overtake front-runner Clinton.
Clinton has said she already considers herself the de facto nominee and is increasingly turning her attention to Donald Trump, saying on Sunday that the rhetoric of the presumptive Republican nominee was dangerous.
Sanders told ABC's "This Week" program that Americans should not have to choose between "the lesser of two evils" in the Nov. 8 election.
Sanders said that if he won the White House, he would not reappoint U.S. Representative Debbie Wasserman Schultz as DNC chairwoman. He also endorsed law professor Tim Canova, who is challenging the Florida congresswoman in the August Democratic primary.
