One hundred former federal prosecutors have signed an open letter written by the Clinton campaign that criticizes FBI director James Comey for commenting to Congress about emails found during an investigation into Anthony Weiner's sexting scandal.

Among the dozens of former federal prosecutors who have added their name to the document is former Attorney General of the United States Eric Holder.

'Many of us have worked with Director Comey; all of us respect him. But his unprecedented decision to publicly comment on evidence in what may be an ongoing inquiry just eleven days before a presidential election leaves us both astonished and perplexed,' the letter says.

Over the weekend, the group of former prosecutors and Department of Justice officials signed Clinton's open letter.

Hillary Clinton's campaign has addressed a draft letter to former federal prosecutors, which implies that they should hammer Comey and criticize his choice to make a public comment about emails found during the investigation into Anthony Weiner's sexting scandal so close to the general election

It begins by saying that during an investigation, information can be incorrect, misleading or incomplete and releasing comments before the facts are in can be prejudiced and dangerous.

'It is out of our respect for such settled tenets of the United States Department of Justice that we are moved to express our concern with the recent letter issued by FBI Director James Comey to eight Congressional Committees,' the letter states.

It goes on to say that Comey allegedly violated 'longstanding Justice Department guidelines' with his choice to make a statement about political figures within 60 days of an election.

'Director Comey's letter is inconsistent with the prevailing Department policy, and it breaks with longstanding practices followed by officials of both parties during past elections,' it continues.

Comey's 'unprecedented decision to publicly comment on evidence in what may be an ongoing inquiry just eleven days before a presidential election leaves us both astonished and perplexed', the letter says.

The Daily Beast was given a draft copy of the letter by a former chief of the criminal division of the U.S. Attorney for the Southern District of New York, Elkan Abramowitz, the site reported.

Abramowitz called Comey's decision 'outrageous'.

'His letter gives away the fact that he doesn’t know what’s in the emails or if it is significant or not. If he doesn’t know if it’s significant, he has no obligation to tell Congress,' he told the Daily Beast.

Abramowitz said the letter Comey sent to Congress is essentially a 'no-news comment'.

He added that he thinks Comey was caught up in his own sense of righteousness and has made a 'really bad' decision for himself and the FBI.

'It’s really bad. Bad for the FBI as well, it makes them look like they’re tilting politically. He’s not all that political a guy. He may be a Republican, but he’s not a partisan,' Abramowitz told the Daily Beast.

Abramowitz added he doesn't believe Comey's argument that he had to go public before a potential email leak was valid.

'Whether he thought there was [going to be] a leak or not, he could comment at that point, one way or the other,' Abramowitz told the site.

He said the issue is Huma Abedin's problem, not Clinton's.

The FBI has obtained a court order to read the emails on Weiner's computer, which have emails to and from Clinton's private server.

As many as 650,000 emails are believed to be on the server, according to the Wall Street Journal.
