A U.S. congressman form Colorado is urging the Bush administration to block the extradition of television bounty hunter "Dog" Chapman to Mexico.

U.S. Rep. Tom Tancredo, R-Colo., sent a letter to U.S. Secretary of State Condoleezza Rice urging her to intercede on behalf of Chapman, who is wanted in Mexico for his 2003 capture of fugitive Max Factor heir Andrew Luster, KCNC-TV in Denver reported Wednesday.

The letter dated Sept. 29 is posted on Tancredo's Web site and suggests that Mexican authorities are trying to save face for their own failure to locate Luster. While bounty hunting is illegal in Mexico, Chapman and Tancredo contend Dog was in contact with Mexican police in 2003 but they allegedly failing to show up when the apprehension was made.

U.S. marshals arrested Chapman, star of the A&E series "Dog: The Bounty Hunter," at his home in Hawaii last month.
