In a phone interview on CNBC's "Closing Bell," Conway discussed the FBI probing newly uncovered emails related to its Clinton investigation. FBI Director James Comey sent a letter to lawmakers Friday explaining that those new emails were discovered during a separate investigation.
"We think it is remarkable and unprecedented to have an investigation 11 days before an election," Conway told CNBC. "When people cast their vote they have to think long and hard. Do you want to elect somebody who may be under indictment or convicted while president of the United States? And so that's a very important question for people to ask. I think Hillary Clinton is too risky and unfit and unqualified to be president."
Conway said she doubts that the Clinton campaign has a "plan B" to respond to such a revelation and added that "no one will be surprised" that there are more emails.
"Majorities of Americans clearly tell pollsters that they don't find her to be honest or trustworthy," Conway said. "You saw during the FBI investigation originally and the press conference on July 5 that many Americans said they disagreed with that, that they're very concerned that she may have violated the law or at least on something that she should not have done."
