Rep. Tom Tancredo plans to leave the U.S. House of Representatives at the end of 2008, whether his longshot presidential bid is successful or not, the Rocky Mountain News reported.

"It's the fact that I really believe I have done all I can do in the House, especially about the issue about which I care greatly (immigration)," Tancredo, 61, told the newspaper Sunday night.

Tancredo, R-Colo., has been an outspoken opponent of illegal immigration. He is in his fifth term in the House.

He said he didn't have a specific career plan in mind for the future.
