Former President George W. Bush, as well as his vice president, Defense secretary, and CIA director should all face a criminal investigation for their alleged authorization of torture and other war crimes during their tenure in office following the 9/11 attacks in 2001, according to a report issued on Tuesday by Human Rights Watch.

In addition to authorizing “waterboarding” and other harsh interrogation tactics, the four men also approved the use of secret CIA prisons overseas and the transfer of terrorism suspects to countries where they were allegedly tortured, the report says.

The human rights group is urging the Obama administration to conduct a broad investigation into how the policies were drafted, adopted, and carried out. The group wants the Obama administration to hold President Bush and other top officials in his administration accountable for what it says were acts of torture and other illegal treatment of detainees in violation of the international Convention against Torture and US law.
