Rep. Mary Bono Mack’s campaign called reporters today, inviting them to Fairfield Inn in Palm Desert. They played audio of what they say is Democratic challenger Dr. Raul Ruiz reading a letter of support in 1999 for a man convicted of murdering two FBI agents.

Moments after The Desert Sun posted the story, we noticed John Pezzullo (a campaign manager for Bono Mack) and Patrick Boland (a spokesman for Ruiz) take their candidates’ campaign battle to Twitter:
