Federal agents foiled a plot by a Vietnam veteran to assassinate three United States senators because he was angry about the Department of Veterans Affairs’ treatment of him.

In a criminal complaint obtained exclusively by RadarOnline.com, law enforcement agents have revealed how James Puchtel, 58, from Linton, IN, made a series of threatening phone calls to VA staffers on February 2, including a recorded phone call in which he said he “wanted to kill” Senator Richard Lugar, Senator Dan Coates and former Democratic Senator Evan Bayh.

Federal agents said they disrupted Puchtel’s plans to go to the lawmakers homes and shoot them “with a rifle as they came out of their house.”

Puchtel was not charged.
