Washington ? U.S. Special Counsel Scott Bloch repeatedly butted heads with a task force he set up to decide whether to investigate high-profile accusations of political meddling by the Bush administration, draft documents released Wednesday show.

A look at 11 subject areas identified for potential investigation, however, shows no apparent partisan pattern or bias by Bloch, a former Lawrence attorney, in deciding whether his office would pursue accusations that political work was being done on government time and property.

Meanwhile, a Republican congressman on Wednesday joined liberal-leaning whistle-blower groups in demanding that Bloch resign immediately. A day earlier, Bloch’s office and home were raided by federal agents as part of a criminal investigation into whether he destroyed evidence potentially showing he retaliated against his own staff.

The Office of Special Counsel is responsible for protecting the rights of federal workers and ensuring that government whistle-blowers are not subjected to reprisals.

“In light of the various investigations into Mr. Bloch’s conduct, including the FBI probe revealed yesterday, it’s hard to believe he can continue to operate effectively,” Rep. Tom Davis, R-Va., the top Republican on the House Oversight and Government Reform Committee, said in a statement. “It’s time the OSC put this turbulent period behind it and return to the important work of protecting federal whistle-blowers.”

Bloch’s attorney, Roscoe Howard, declined comment.

The new documents, released Wednesday by the watchdog group Project on Government Oversight, detail 11 subject areas the Office of Special Counsel’s task force identified for potential investigation.

In more than half of the cases, according to the draft report dated Jan. 18, 2008, Bloch and the task force disagreed on whether an investigation should be pursued or closed.
