Ethan Barton of the Daily Caller highlights a colleague’s unflattering assessment of controversial former IRS official Lois Lerner.

Disgraced former IRS official Lois Lerner, made famous by the agency’s conservative targeting scandal, was a “volatile” “micromanager” who “targets people,” her colleagues told the FBI.

Lerner headed the IRS office that targeted conservative and Tea Party non-profit applicants. She sent their tax exemption applications to a bureaucratic “black hole” prior to and after the 2012 election, FBI interviews obtained by the conservative watchdog Judicial Watch show.

The documents reveal a side of Lerner’s disruptive personality that was previously unreported. The interviews were conducted in 2013 and 2014.

“Lerner is very volatile,” top IRS official Nancy Marks told the FBI. “When something upsets Lerner, she flies up into the rafters and yells and targets people, then she settles down and figures it out in a rational manner. She then becomes very reasonable again.”

Lerner told the FBI that she went “ballistic” during a meeting where she learned about the Tea Party targeting.

“Lerner yelled and raised her voice at the meeting,” the FBI wrote of her testimony. “[S]he is passionate and tended to get loud when that happened.”

Lerner “had a tendency to blow up,” an unidentified IRS senior technical adviser told the FBI.
