CONCORD, N.H. -- On the eve of the New Hampshire primary, Bernie Sanders’s campaign manager accused Hillary Clinton’s campaign of being in “disarray” as he sought to bat down the latest line of attack from the rival Democratic presidential camp.

Jeff Weaver, Sanders’s campaign manager, said in a statement Monday that it was “very disturbing that as the Clinton campaign struggles through Iowa and New Hampshire they have become increasingly negative and dishonest.”

The statement was prompted by Clinton earlier Monday accusing Sanders of engaging in the same behavior for which he has repeatedly criticized her: taking donations from Wall Street.

In Sanders’s case, the allegation isn’t that he took money directly but that his campaign accepted financial help from the Democratic Senatorial Campaign Committee, which had raised money from Wall Street firms.

"You know, Senator Sanders took about $200,000 from Wall Street firms, not directly, but through the Democratic Senatorial Campaign Committee,” Clinton told her audience in Manchester. "There's nothing wrong with that. It hasn’t changed his view.”

Weaver said that to arrive at the $200,000 figure, Clinton would have to assume that “every nickel” the DSCC transferred to Sanders for his Senate campaign and the Vermont Democratic Party in 2006 was raised from Wall Street firms, a notion he said was “absurd,” given the organization raises money from a wide range of sources.

“To say that every nickel that Bernie received came from Wall Street is beyond preposterous,” Weaver said. “It is laughable and suggests the kind of disarray that the Clinton campaign finds itself in today.”

Clinton has said in recent days that Sanders is trying to “smear” her by insinuating that she can be bought by Wall Street and other special interests. Her advisers have accused Sanders of running a far more negative campaign than she is.

During his first two campaign stops of the day Monday in New Hampshire, Sanders made no direct references to Clinton in his stump speeches. Polls have showed him with a sizable lead heading into Tuesday’s contest.

In his statement, Weaver cited several other attacks from the Clinton campaign, including some in the days leading up to the Iowa caucuses, that he considered dishonest. Those included attempts to discredit Sanders’s proposal to a move to a single-payer health-care system.
