This is bad news for anyone who cares about transparency and accountability in government.

Politico's Ken Vogel reports Thursday that Citizens for Responsibilty and Ethics in Washington has been taken over by conservative attack dog-turned-Democratic lapdog David Brock and will likely become part of his partisan operation.

Though left-leaning, CREW was most definitely nonpartisan and has been a reliable source of information for reporters on government corruption, as well as an advocate for action against members of Congress who violate ethics rules.

Vogel reports that a greatly expanded CREW will now become part of Brock's web of partisan organizations that provide opposition research and attack services for Democrats independent of the official party structure. His organizations have spent a lot of time preparing for a possible Hillary Clinton candidacy in 2016, by fending off attacks on her.

“CREW gives us some potentially powerful tools in the tool box,” Brock told Vogel in an interview. “We have been in the accountability for 10 years very successfully. It is kind of a one-stop-shop now.”

Translation: Delete CREW from your source list, Washington reporters. It's not going to be reliable anymore.
