The donations poured into the campaign through the online fundraising site ActBlue.
Correct the Record, a super-PAC led by Clinton ally David Brock, sent an email out on Monday comparing Sanders to British Labour Party leader Jeremy Corbyn, a committed socialist.
The attack linked Sanders, who identifies as a Democratic socialist, to controversial remarks made by Corbyn, including his praise of the late Venezuelan president Hugo Chávez.
The email also quoted Corbyn calling the death of Osama bin Laden “a tragedy,” as there was no attempt to arrest and put the al Qaeda leader on trial.
Sanders’s campaign blasted out a fundraising email in response to the super-PAC.
“Yesterday, one of Hillary Clinton’s most prominent Super PACs attacked our campaign pretty viciously,” an email sent by the Sanders campaign on Tuesday read.
“It was the kind of onslaught I expect to see from the Koch Brothers or Sheldon Adelson, and it’s the second time a billionaire Super PAC has tried to stop the momentum of the political revolution we’re building together.”
Sanders spokesman Michael Briggs said the super-PAC was “distorting the record.”
“It is disappointing that Secretary Clinton’s super-PAC is spreading disinformation about Bernie,” Briggs said. “This is exactly the kind of politics that Bernie is trying to change.”
Clinton herself has so far refused to take shots at Sanders and other Democratic candidates, focusing most of her attention on the Republican field.
