WASHINGTON -- A coalition of liberal groups filed petitions Monday seeking disbarment of Bush administration attorneys linked to memos on harsh interrogation techniques of detainees. 

Complaints were filed against 12 individuals, including former attorneys general John Ashcroft, Alberto Gonzales and Michael Mukasey and former Homeland Security Secretary Michael Chertoff, said a member of the groups. The complaints filed with bar associations in the District of Columbia and four states -- New York, California, Texas and Pennsylvania -- say their licenses should be revoked for "moral turpitude." 

"These lawyers misused their license to practice law to provide legal cover for the war crime of torture," said Kevin Zeese, executive director of VotersForPeace.US and a board member with VelvetRevolution.US, the two groups leading the effort. 

Memos by the Bush Justice Department contended that waterboarding -- a form of simulated drowning -- as well as sleep deprivation and other extreme techniques were legal under U.S. and international law. 

The other attorneys who are targets of the campaign are: 

-- John Yoo, Jay Bybee and Stephen Bradbury, who worked in the Justice Department's Office of Legal Counsel 

-- Ex-Undersecretary of Defense Douglas Feith 

-- Former Vice President Dick Cheney's chief of staff, David Addington 

-- Pentagon lawyer William Haynes 

-- Former deputy White House counsel Timothy Flanigan 

-- and Alice Fisher, former director of the Justice Department's Criminal Division.
