SALT LAKE CITY (AP) -- GOP U.S. Sen. Bob Bennett is continuing to attract Republican challengers.
On Monday, Mike Lee and Tim Bridgewater filed to seek the Republican nomination. They join David Chiu and Leonard Fabiano, who filed last week. More challengers are expected to file later this week.
Bennett has come under fire from some Republicans for not being conservative enough following his support for a bailout of the nation's financial industry.
Republicans will choose their nominee in May. Bennett is seeking a fourth term in office.
