Donald Trump's campaign manager ripped Hillary Clinton on Sunday for "playing the victim" and launching an "all-out assault" on FBI Director James Comey, who announced in a letter to Congress last week that the bureau had reopened its investigation into the Democratic presidential hopeful.

"She set off this chain of events and she can't escape that," Kellyanne Conway told NBC. "She's playing the victim now. They're doing an all-out assault on FBI Director James Comey; I mean really shooting the messenger, plus a full-body slam all day yesterday."

Clinton and her top surrogates have called the the FBI's decision to revisit the Clinton case 10 days before the Nov. 8 election "unprecedented" and "disturbing," and urged Comey to provide additional information about his decision and the content of the emails investigators found on a device used by Clinton aide Huma Abedin's estranged husband, Anthony Weiner.

"What we're concerned and disturbed by is that Director Comey sent a letter saying we have some information," Clinton campaign manager Robby Mook said "Fox News Sunday." He continued, "This unprecedented announcement of new information when it's been reported ... that the FBI may have not even seen it, that Director Comey sent this unprecedented letter shortly before the election when he doesn't even know what the information is."

"What's unprecedented and indeed unnecessary is [Clinton] having that private server in the first place," Conway countered on NBC.

"I think it's incredibly ironic that this stems from another investigation, it has nothing to do with the Republican Party or the Trump campaign, into Anthony Weiner's sexting. So this is on them," she added.

Conway also said that Comey, who declined to recommend that Clinton be indicted earlier this summer, should not play victim either as he continues to come under fire from Democrats.

"Had he done a thorough investigation in the first place and made sure that device had been handed over, then maybe we wouldn't be in this position," she said, referring to the device belonging to Weiner on which thousands of emails were recently found.
