WASHINGTON, Jan. 12 (UPI) -- The inspector general at the U.S. Department of Justice said Thursday he will investigate the department and the Federal Bureau of Investigation to determine whether they violated policy with their actions in the final months before November's presidential election.
Democrats criticized FBI Director James Comey for his part in the controversy -- announcing potential new evidence related to the Hillary Clinton email investigation about a week before the vote on Nov. 8.
On Thursday, Justice Department Inspector General Michael Horowitz said his inquiry will focus on whether the bureau's actions violated DOJ or FBI policy. Inspectors general at the department almost never publicize their investigations.
The IG's decision follows multiple requests from congressional lawmakers for a look into pre-election activity in the department -- including House Oversight Committee Chairman Jason Chaffetz, R-Utah; Senate Judiciary Committee Chairman Chuck Grassley, R-Iowa; and Senate Appropriations Committee ranking member Patrick Leahy, D-Vt.
Comey, a Republican-turned-Independent, said he made the new evidence public in the interest of transparency -- but because he didn't disclose many details, Democrats feel it delivered a knockout blow to Clinton at the worst possible time.
"We are 11 days out from perhaps the most important national election of our lifetimes. The American people deserve the full and complete facts immediately," Clinton said at a Oct. 28 rally in Iowa. "The American people deserve to get the full and complete facts immediately."
Two days before the election, Comey announced that the renewed inquiry -- which focused on a laptop belonging to former Rep. Anthony Weiner, who was married to a Clinton aide -- had turned up nothing new. Democrats, though, said substantial damage had already been done.
Less than 48 hours later, Trump was declared the 45th president of the United States -- thanks to narrow victories in several battleground states, including Wisconsin and Michigan, which hadn't voted Republican for more than 30 years.
The Office of the Inspector General said its review will not supersede the FBI's conclusion in the case, that Clinton should not face criminal charges for the handling of her private email server while secretary of state.
"The review will not substitute the inspector general's judgment for the judgments made by the FBI or the Department regarding the substantive merits of investigative or prosecutive decisions," Horowitz's office said in a statement. "If circumstances warrant, the OIG will consider including other issues that may arise during the course of the review."
White House spokesman Josh Earnest said Thursday that President Barack Obama was not involved in Horowitz's decision to open the inquiry. The inspector general, a former Democratic supporter who donated to Clinton when she was a senator for New York, was appointed to the post by Obama in 2011.
"Hopefully they will follow the evidence where it leads," he added.
Obama, who appointed Comey to his post, criticized the FBI director for his actions in October. Some lawmakers alleged Comey had violated the Hatch Act, a federal law that bars government officials from influencing an election.
It was later revealed that several Justice Department officials advised Comey against announcing the Clinton inquiry so close to the election. They argued that the act ran contrary to department tradition of withholding announcements involving political candidates within 30 days of an election -- a stipulation that exists specifically to avoid making an adverse impact on the vote.
Comey himself acknowledged the tradition in an internal memo to FBI employees.
"We don't ordinarily tell Congress about ongoing investigations, but here I feel an obligation to do so given that I testified repeatedly in recent months that our investigation was completed," he wrote. "I also think it would be misleading to the American people were we not to supplement the record."
Former Justice Department spokesman Matthew Miller said at the time that Comey's actions may be unprecedented.
"[This] disclosure might be worst abuse yet. DOJ goes out of its way to avoid publicly discussing investigations close to election," he said in a tweet. "This might be totally benign and not even involve Clinton. But no way for press or voters to know that. Easy for opponent to make hay over."
For about a year, the FBI investigated Clinton's use of a personal email server while she was Obama's State Department head to determine whether any classified information had been sent or received on the unsecure account.
In July, Comey announced that nothing illegal involving Clinton had been uncovered, and Attorney General Loretta Lynch said the case would be closed without charges.
Horowitz's investigation will also evaluate concerns by Republicans that a department liaison passed on nonpublic information to Clinton's campaign before the election, and that FBI Deputy Director Andrew McCabe should have been removed from the case due to pre-existing political ties to Clinton.
