At least not from the legislative or executive branch. The rendition program actually started under Clinton in 1995. Any investigation into war crimes, if it is a serious investigation, will end up going back to the Clinton white house and possibly indict Clinton, Gore, as well as several higher ups in his administration for their role in torture. Also all the dems who helped cover up these acts in the Bush admin could be culpable.
http://www.everythingiknowiswrong.com/2005/12/cia_rendition_p.htmlMichael Scheuer, a 22-year veteran of the CIA who resigned from the agency in 2004, has told Die Zeit that the US administration had been looking in the mid-1990s for a way to combat the terrorist threat and circumvent the cumbersome US legal system.
"President Clinton, his national security adviser Sandy Berger and his terrorism adviser Richard Clark ordered the CIA in the autumn of 1995 to destroy Al Qaeda," Mr Scheuer said.
"We asked the president what we should do with the people we capture. Clinton said 'That's up to you'."
Mr Scheuer, who headed the CIA unit that tracked Al Qaeda leader Osama bin Laden from 1996 to 1999, says he developed and led the "renditions" program.

In 1993, Richard Clarke, the former chief of counter-terrorism on the U.S. National Security Council urged the administration of President Bill Clinton to conduct the first extraordinary rendition. According to Clarke, Al Gore admitted the program’s illegality, but urged Clinton to go ahead with the practice covertly.<7> There are, however, numerous legal issues involved in the extraordinary rendition process, and it is uncertain which issue or issues Gore felt illegal.
Anyway, I support investigations and feel anyone of any party should be held accountable for breaking the law. But realistically a serious investigation is not going to come from democratic politicians because any serious investigation will find some of them complicit in crimes or it will be full of coverups so only republicans are found guilty. Either way its not going to be a real investigation. Obama isn't going to conduct investigations that could put Clinton and Gore in prison as well as Cheney and Bush.
Realistically, its best to (I know little about the legal system but this is my view) go through international or domestic judicial systems rather than democratic politicians in the executive and legislative branches. My expectation is Obama will call for 'healing' in the form of focusing on the future and will try to cover it up.
