Federal officials said Monday (November 4th) that they'd arrested a 27-year-old man who'd repeatedly expressed anti-Semitic and white supremacist views in a plot to bomb an historic synagogue in Colorado.Richard Holzer was arrested Friday just after undercover agents who pretended to be in on the plot brought him what he thought were two pipe bombs and 14 sticks of dynamite to use to bomb Temple Emanuel in Pueblo. The investigation into Holzer began after an undercover FBI agent pretending to be a woman who supports white supremacy contacted him on Facebook.
