Media Matters chief David Brock paid a former domestic partner $850000 after being threatened with damaging information involving the organizations donors and the IRS a deal that Brock later characterized as a blackmail payment according to legal documents obtained by FoxNews.com.
In an acrimonious lawsuit settled at the end of last year Brock accused William Grey of making repeated threats to expose him to the scorn or ridicule of his employees donors and the press in demanding money and property. Brock claimed in legal papers that he sold a Rehoboth Beach Del. home he once shared with Grey in order to meet Greys demands which he called blackmail in the lawsuit.
- Brock 49 heads the non-profit Media Matters for America which bills itself as a watchdog of the conservative media but has recently come under fire for allegedly coordinating with Democrats in what could be a violation of its tax-exempt status.
Brocks bitter legal battle with Grey who is described in a Sept. 14 2010 police report obtained by FoxNews.com as his domestic partner of more than 10 years began after Brock began dating Washington D.C. restaurant impresario James Alefantis about five years ago. For the next three years Brock and Grey traded angry accusations which were documented in the police report and were the foundation of a pitched legal battle replete with charges of blackmail theft and financial malfeasance.

Alefantis was also named as a defendant in Greys lawsuit.
In his response to Brocks lawsuit Grey denies that he committed any acts of blackmail.
Grey threatened to go public about Brock and Media Matters finances after he accused Brock in a civil suit filed in Washington of taking
$170000 in possessions including an $8000 Louis Vuitton suit bag paintings a rug a chandelier a painted bust of a Roman soldier and a pair of carved wooden chairs upholstered with purple fabric. Those possessions were displayed in the Washington townhouse where the couple entertained liberal movers and shakers in happier times.
Brock took Greys threats seriously and called police in 2010. In the police report filed by Metropolitan Police as a stalking incident Brock accused Grey also 49 of attempting to blackmail him with a series of emails threatening to release specific derogatory information about Brock and his organization to the press and donors that would be embarrassing to him and cause harm to the organization …
Some of those emails came out as the lawsuit filed by Grey on Jan. 28 2011 wound its way through Superior Court of the District of Columbia last year.

Please finish this today so I dont have to waste my time emailing anyone Biden Coulter Carlson Huffington Drudge Ingraham Grey wrote in a 2008 email.
Nearly two years later Grey accused Brock of financial malfeasance and threatened to undermine Brocks fundraising efforts.
Next step is I contact all your donors and the IRS Grey wrote in an email dated May 19 2010. This is going to stink for you if you do not resolve this now.
Brock said in court papers that he paid Grey under duress.
On March 8 2011 Brock filed his own suit against Grey for more than $4 million demanding Grey return the $850000 plus pay millions more in punitive damages. The two settled two months ago under terms that remain confidential.

Paying off Grey may not have been easy for Brock even with his salary of nearly $300000 at Media Matters. Records show Brock had pulled massive amounts of equity from the six-bedroom Rehoboth Beach house as its value skyrocketed during the real estate bubble.
Sussex County property records show he took out a $273000 mortgage to buy the pale yellow colonial and carriage house for $606666 in 1995. As the converted inn built in 1793 continued to rise in value Brock refinanced his loan on at least two occasions. Records show he had a $1.44 million mortgage on the property as well as two more loans against the home totaling just over $500000.
Brock received $1587500 for the home on May 25 2010 in a sale to McLean Va.-based Vardell Realty Investments. It could not be determined how much Brock still owed on the $1.44 million mortgage or how much he netted from the sale if any.
Records indicate that Brock had paid off the two smaller loans at the time of the sale.
Within a year of selling the house Brock apparently had second thoughts about paying off Grey. In the civil suit Brock accused Grey of three counts of blackmail citing a statute that defines blackmail as threatening to expose a secret or publicize a fact whether true or false tending to subject any person to hatred contempt or ridicule to impair the reputation of any person.
He countersued to get his $850000 back plus $500000 for each of three counts of alleged blackmail and another $2 million in compensatory damages based in part on what Brocks lawyers called abuse of the judicial system and legal fees.
Grey who relocated to Massachusetts declined to comment when contacted by FoxNews.com. Brock and Alefantis remain in Washington where Brock has released a new book attacking Fox News. He is also under scrutiny from several members of Congress amid reports Media Matters for America is in possible violation of IRS laws governing nonprofits.
The Rehoboth Beach home was torn down months after Brock sold it amid much community opposition so the buyer could divide the parcel and build two homes. It remains a vacant lot.
