Source: New Clinton Emails Discovered During Anthony Weiner Sexting Investigation

Conway: Trump Has Significant 'Undercover' Support; Hillary Has None

Republican National Committee Chairman Reince Priebus joined Neil Cavuto today to react to the FBI's stunning decision to reopen its investigation into Hillary Clinton’s use of a private after discovering new emails during the probe of  Anthony Weiner’s sexting.

FBI Director James Comey wrote in a letter to top members of Congress Friday that the bureau has “learned of the existence of emails that appear to be pertinent to the investigation.”

"My guess is that it's pretty serious, and it wouldn't have happened today if it wasn't," Priebus said.

He noted that the Clinton campaign called the decision to revisit the case so close to the election “extraordinary,” urging Comey to provide more details.

Priebus actually agreed with that statement and argued it reinforces the stance of Republican leaders.

"Why would an FBI director inform the entire highest levels of our congressional leadership in these particular areas of this matter if it wasn't something extraordinarily serious?" Priebus asked.

He added that Clinton should not have avoided charges in the first place, and the Democratic nominee simply can't be trusted with the presidency.
