(ABC News) -- Former federal prosecutors and high-ranking Department of Justice officials, including former Attorney General Eric Holder, penned an open letter criticizing FBI Director James Comey's handling of the latest development in the investigation into Hillary Clinton's use of a private email server.
"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 said.
Comey sent a letter to top leaders in Congress Friday informing the members that the bureau was reviewing additional emails possibly related to Hillary Clinton's personal server, after it learned of new information that might be relevant to the case.
The emails that prompted the FBI review came from a separate federal investigation of former Rep. Anthony Weiner. Federal prosecutors have been looking at whether Weiner sent an explicit text message to an underage girl in North Carolina.
The letter sent by former DOJ officials was circulated by the Clinton camp Sunday.
