Report on FBI probe into Trump campaign's ties to Russia finds mistakes, no sign of political bias

The FBI was justified in opening its investigation into ties between the Trump presidential campaign and Russia, and didn't act with political biasdespite "serious performance failures" up the bureau's chain of command, the Justice Department's internal watchdog said in a highly anticipated report Monday.

The findings of the report, released by department Inspector General Michael Horowitz, seemingly undercuts U.S. President Donald Trump's claim he was the target of a "witch hunt."

The long-awaited report rejected theories and criticism spread by Trump and his supporters, though it also found a number of errors that Republicans are citing as evidence that Trump was targeted by an unfair investigation.

The affirmation of the investigation's legitimacy, balanced by criticism of the way it was conducted, ensured that partisan battles would persist over one of the most politically sensitive investigations in FBI history. Another review of the origins of the probe continues, and the prosecutor picked by Attorney General William Barr to lead that effort hinted Monday he'll take a harder view of the FBI's actions.

Monday's reviewknocked down multiple lines of attack against the Russia investigation, finding that it was properly opened and that law enforcement leaders were not motivated by political bias. Contrary to the claims of Trump and other critics, it said that opposition research compiled by an ex-British spy named Christopher Steele had no bearing on the decision to open the investigation known as Crossfire Hurricane. And it rejected allegations that a former Trump campaign aide at the centre of the probe was set up by the FBI.

It found that the FBI had an "authorized purpose" when it opened its investigation in July 2016 into whether the Trump campaign was co-ordinating with Russia to tip the election in his favour. The report said the FBI had cause to investigate a potential national security threat.

FBI taking 40 corrective actions

In an interview with The Associated Press, FBI Director Chris Wray said the inspector general found problems that are "unacceptable and unrepresentative of who we are as an institution." But he also noted that political bias did not taint the opening of the investigationor the steps that followed.

He said the FBI is implementing more than 40 corrective actions aimed at fixing some of the bureau's most fundamental operations, such as applying for surveillance warrants and interacting with confidential sources.

Those changes are in response to some of the report's criticisms. They largely centred on how agents and prosecutors set about eavesdropping on a former Trump campaign aide who they said they feared was being targeted for Russian government recruitment.

The inspector general identified17 "significant errors or omissions" inapplications for a warrant from the secretive Foreign Intelligence Surveillance Court to monitor the communications of former Trump campaign adviser Carter Page and subsequent warrant renewals.

The report also details that the FBI used an informant to set up and record a September 2016 meeting with a high-level Trump campaign official. The official wasn't identified by name, but was not a subject of the Russia investigation, the report said. While the information collected wasn't used during the Russia probe, it does lend support to the assertions by Trump and Barr that the Trump campaign was spied upon.

The errors, the watchdog said, resulted in "applications that made it appear that the information supporting probable cause was stronger than was actually the case."The watchdog found the FBI had overstated the significance of the past work of Steele as an informant andomitted information about one of Steele's sources, who the former spy had called a "boaster" and said may have engaged "in some embellishment."

Political divisions evident in responses

Republicans have long criticized the process since the FBI relied in part on opposition research from Steele, whose work was financed by Democrats and the Clinton campaign, and that fact was not disclosed to the judges who approved the warrant.

Though the surveillance has been central to Republican objections about the investigation, the eavesdropping was not necessarily central to the probe itself which had been underway for months before the warrant was sought.

The report's releaseon the same day as a House judiciary committee impeachment hearing centred on the president's interactions with Ukrainebrought fresh attention to the legal and political investigations that have entangled the White House from the moment Trump took office.

Political divisions were evident in responses to the report.

Senate Democratic leader Chuck Schumer said it makes clear that the basis for the FBI's investigation was "valid and without political bias." Trump, in remarks at the White House, claimed it showed "an attempted overthrow and a lot of people were in on it."

The president hasrepeatedly said he was more eager for the report of John Durham, the hand-picked prosecutor selected by Barr to investigate how intelligence was gathered.

Both Barr and Durham issued statements rejecting the inspector general's conclusion that there was sufficient evidence to open the FBI investigation. The attorney general's reaction was especially unusual in that the head of the Justice Department typically would not take issue with an internal investigation that clears a department agency of serious misconduct.

"The inspector general's report now makes clear that the FBI launched an intrusive investigation of a U.S. presidential campaign on the thinnest of suspicions that, in my view, were insufficient to justify the steps taken," Barr said in a statement.

Durham, in a brief statement, said he has informed the inspector general that he also doesn't agree with the conclusionthe inquiry was properly opened, and suggested his own investigation would back up that assertion.

The FBI's Russia investigation, which was ultimately taken over by special counsel Robert Mueller, began in July 2016 after the FBI learnedformer Trump campaign aide George Papadopouloshad been saying before it was publicly known that Russia had dirt on Democratic opponent Hillary Clinton in the form of stolen emails. Those emails, which were hacked from Democratic email accounts by Russian intelligence operatives, were released by WikiLeaks in the weeks before the election in what U.S. officials have said was an effort to harm Clinton's campaign and help Trump.

The report concluded that that revelation was a sufficient basis foropening the investigation and it knocked down claims by Papadopoulos that he had been set up by the FBI or that the professor who told him about the hacked emails was an FBI informant.

Months later, the FBI sought and received the Page warrant. Officials were concerned Page was being targeted for recruitment by the Russian government, though he has denied wrongdoing and has never been charged with a crime.

More than 170 interviews conducted

The inspector general also found an FBI lawyer is suspected of altering an email to make it appear as if an official at another government agency had said Page was not a source for that agency, even though he was.

Agents were concerned that if Page had worked as a source for another government agency, they would haveneeded to tell the surveillance court about that, the report said, and contacted the other agency to obtain additional information. But the FBI lawyer "did not accurately convey, and in fact altered, the information he received from the other agency," the report said.

The lawyer is not identified by name in the report, but people familiar with the situation have identified him as Kevin Clinesmith. The inspector general's report says officials notified the attorney general and FBI director, and provided them with information about the altered email.

The inspector general conducted more than 170 interviews involving more than 100 witnesses.
