David Brock is a longtime Clinton ally, self-described liar and the paranoid founder of Media Matters. Some background on him:

David Brock was smoking a cigarette on the roof of his Washington, D.C. office one day in the late fall of 2010 when his assistant and two bodyguards suddenly appeared and whisked him and his colleague Eric Burns down the stairs.



Brock, the head of the liberal nonprofit Media Matters for America, had told friends and co-workers that he feared he was in imminent danger from right-wing assassins and needed a security team to keep him safe.



The threat he faced while smoking on his roof? “Snipers,” a former co-worker recalled.



“He had more security than a Third World dictator,” one employee said, explaining that Brock’s bodyguards would rarely leave his side, even accompanying him to his home in an affluent Washington neighborhood each night where they “stood post” to protect him. “What movement leader has a detail?” asked someone who saw it.



Extensive interviews with a number of Brock’s current and former colleagues at Media Matters, as well as with leaders from across the spectrum of Democratic politics, reveal an organization roiled by its leader’s volatile and erratic behavior and struggles with mental illness, and an office where Brock’s executive assistant carried a handgun to public events in order to defend his boss from unseen threats.

Five years ago, Brock came up with an extensive plan to impeach conservative Supreme Court Justice Clarence Thomas. He sent a memo in October 2010 to then Secretary of State Hillary Clinton on her personal email address detailing his plan and salacious "evidence" justifying his argument for impeachment. The memo was revealed late last night as part of the State Department's obligation to turn over thousands of Clinton's emails as ordered by a federal judge.

Brock Memo - Impeach Thomas

Brock accuses Thomas of engaging in multiple affairs, watching pornography at the work place, intimidating witnesses and more.

Brock has been at the forefront of defending Hillary Clinton since allegations of trading political favors at the State Department for donations to the Clinton Foundation emerged earlier this year. He went after Peter Schweizer, author of Clinton Cash, after he exposed the practice.

Brock's specialty is character assassination at all costs, with zero proof to sustain his allegations. His attack on Thomas is unsurprising.
