Hillary Clinton Says ‘Nobody Likes’ Bernie Sanders and Declines to Commit to Backing Him

“It’s his leadership team. It’s his prominent supporters. It’s his online Bernie Bros and their relentless attacks on lots of his competitors, particularly the women,” she said. “And I really hope people are paying attention to that because it should be worrisome that he has permitted this culture.”

“Not only permitted,” she added, but he “seems to really be very much supporting it.”

In a statement on Tuesday responding to Mrs. Clinton’s remarks, Mr. Sanders said: “My focus today is on a monumental moment in American history: the impeachment trial of Donald Trump. Together, we are going to go forward and defeat the most dangerous president in American history.”

Over a grueling primary battle through 2015 and 2016, Mrs. Clinton and Mr. Sanders clashed over policy differences over trade, the war in Iraq and others issues, and occasionally veered into more personal territory. On the campaign trail and in televised debates, Mr. Sanders attacked her ties to wealthy donors and Wall Street banks, including her six-figure speaking fees from Goldman Sachs. Mrs. Clinton pushed back hard, calling him out for being unable to cite evidence that she was unduly influenced by banks, and portraying him as lacking in policy specifics and nuances.

Mr. Sanders won nearly 13 million votes in the 2016 primary presidential contests against Mrs. Clinton, and beat her in key states like Michigan, New Hampshire and Wisconsin. He also won more than 1,800 Democratic delegates. He initially refused to end his campaign in June 2016 after Mrs. Clinton secured the nomination, but eventually endorsed Mrs. Clinton as the convention neared. Still, many die-hard Sanders supporters remained critical of Mrs. Clinton’s candidacy through the general election, in online comments and in interviews, and Mr. Sanders did not unite them behind her.

Months later, in the general election, Mrs. Clinton won the popular vote but lost the Electoral College majority to Mr. Trump.

Mrs. Clinton also said that she had spoken with Ms. Warren, Senator Amy Klobuchar of Minnesota and “practically everybody” who is seeking the Democratic nomination. But according to a transcript of the Hollywood Reporter interview, she nodded when the questioner suggested that Mr. Sanders was “not part of that.”

“I can’t say all of them,” she said of the candidates she had spoken with.
