Senate Judiciary Chairman Patrick Leahy (D-Vt.) on Wednesday announced his committee would hold hearings on the creation of a new truth commission to investigate myriad allegations of corruption and wrongdoing in the Bush administration.

Leahy said in a Senate floor speech that understanding what occurred during the previous administration is key to avoiding the same mistakes in the future.

“The past can be prologue unless we set things right. … How can we restore our moral leadership and ensure transparent government if we ignore what has happened?” Leahy said.

Leahy first floated the idea earlier this month during a speech at Georgetown University. Although Republicans have resisted the proposal, Leahy and other Democrats argue it would provide a nonpartisan way to conduct investigations without the threat of legal repercussions against those who cooperate.

The hearing is scheduled for March 4, according to Leahy’s office.
