In reporting the movement to impeach the president, I interviewed lawyers who said that theoretically, George W. Bush could be vulnerable to a wide array of punishments and lawsuits if members of Congress, and the public at large, suspect him of breaking the law.
A German prosecutor is seeking a criminal investigation into former Defense Secretary Donald Rumsfeld and other administration officials over abuse at Abu Ghraib and GuantÃ¡namo. That prosecutor could also seek charges for Bush as commander in chief of the military.
On US soil, prosecutors could also pursue charges against Bush and other administration officials. John Bonifaz, co-founder of After Downing Street, said that as an example, a "courageous prosecutor" could gather military families as plaintiffs in a case over deception leading into the war in Iraq.
But those I interviewed admitted that lawsuits against Bush are not likely to withstand presidential immunity.
Congress members can also censure the president, a symbolic gesture that could show the president the level of disapproval directed at him.
Michael Seidman at the Georgetown Law Center said that using its power of the purse, Congress could even cut off funding for executive branch services such as Air Force One.
