Vice Presidential candidate Sen. John Edwards was caught visiting his mistress and secret love child at 2:40 this morning in a Los Angeles hotel by the NATIONAL ENQUIRER. The married ex-senator from North Carolina - whose wife Elizabeth continues to battle cancer -- met with his mistress, blonde divorcée Rielle Hunter, at the Beverly Hilton on Monday night, July 21 - and the NATIONAL ENQUIRER was there! He didn't leave until early the next morning. Rielle had driven to Los Angeles from Santa Barbara with a male friend for the rendezvous with Edwards. The former senator attended a press event Monday afternoon with L.A. Mayor Antonio Villaraigosa on the topic of how to combat homelessness. But a months-long NATIONAL ENQUIRER investigation had yielded information that Rielle and Edwards, 54, had arranged to secretly meet afterward and for the ex-senator to spend some time with both his mistress and the love child who he refuses to publicly acknowledge as his own.
