Senator John Cornyn is the latest Republican to call for US Attorney General Eric Holder's resignation. The call came during a heated exchange during a Senate Judiciary committee hearing today.

Cornyn accused Holder of "violating the public trust" and said he hoped "President Obama appoints someone who is up to the challenge" of putting justice before politics.

Cornyn has been one of Holder's biggest opponents and opposed his 2009 nomination. However, he'd held back on calling for his resignation, until now.

Holder could face contempt charges in the wake of the 'Fast and Furious' gun walking scandal.
Many Republicans have questioned what Holder knew about the passing of illegally purchased weapons across the boarder to suspected weapon smugglers Mexico. Those weapons would eventually land in the hands of Mexican drug cartel members and one would be used to shoot and kill a US Border Patrol agent.

Cornyn also questioned Holder's refusal to appoint a special prosecutor to investigate leaks of confidential information to the media.

Holder rejected Cornyn's call to step down. He said, "I don't have any intention of resigning. I heard the White House press officer say yesterday that he has absolute confidence in me. I don't have any reason to believe that, in fact, is not the case."

The House Oversight committee with discuss the contempt charges on June 20.
