Anger, disbelief in Clinton camp, by Amie Parnes.

Hillary Clinton’s allies were cast into a state of anger and disbelief over the FBI’s stunning announcement that it is reviewing new emails “pertinent” to Clinton’s use of a private email server.

That shocking development — revealed in a letter to Congress by FBI Director James Comey — pushed some of Clinton’s allies past the boiling point.

They said they were “dumbfounded” by the revelation that the new FBI review may have been spurred by a separate investigation into Anthony Weiner sending lewd texts to a minor. Weiner is separated from wife Huma Abedin, one of Clinton’s closest aides.

And they worried that Clinton’s unconventional email arrangement had finally caught up to her and might imperil her presidential bid less than two weeks before Election Day. …

Another ally called the campaign’s mood something akin to “paralysis,” and blamed Weiner’s behavior for railroading the campaign.

One strategist said the developments would further cement the notion that Clinton has something to hide.
