A group of lawmakers lead by Rep. Dana Rohrabacher, R-Calif., are calling on the Department of Justice to investigate the treatment of two former Border Patrol agents who are serving prison terms for the controversial 2005 shooting of a drug-running illegal immigrant.

Rohrabacher and more than three dozen fellow congressmen are signing onto a letter, calling for the probe, to be delivered to Michael Mukasey, who is expected to soon win Senate approval as U.S. attorney general, The Washington Times reported Tuesday.

The lawmakers said the agents, Ignacio Ramos and Jose Compean, are living in conditions worse than those facing suspected terrorists at Guantanamo Bay, Cuba.

"We request that you conduct a fair and unbiased review of this case and take any action to rectify this injustice. ... As the nominee to be the next attorney general, we urge you to investigate the case against these two agents, who we believe acted in accordance with their duties to enforce the law, as well as take the action to rectify the mistreatment of Ignacio Ramos, and move him to a minimum-security facility," the letter says.

Compean and Ramos were convicted in October 2006 for the non-fatal shooting in February, 2005. Ramos received an 11 year sentence; Compean's sentence is 12 years.
