PROVO, Utah -- President Bush is taking sides in a hot Utah congressional race.

Cannon needs support from 60 percent of the delegates or he'll face a primary election. His challengers are Jason Chaffetz, a former aide to Gov. Jon Huntsman, and Dave Leavitt, the brother of former Utah Gov. Mike Leavitt.

In the endorsement letter, Bush says it's important to have Cannon return to Washington for another two-year term. The Salt Lake Tribune reported the letter on its Web site Monday.

Bush also endorsed Cannon when he had Republican opposition in 2006.
