Doran Kaye's background was first reported Friday by The Colorado Observer. Kaye volunteered his resignation the same day.
Kaye, 37, began working for the campaign on August 12, 2011. Kaye's Linkedin webpage described his role as a "call center supervisor" responsible for "recruiting, training and supervising" call center employees. The Miklosi campaign said he was a part-time worker.
Kaye's criminal history includes felony drug arrests in 2006 and 2007 along with a pattern of failing to appear in court to answer to those charges. Kaye has served jail time on several occasions.
A call to Kaye's home Friday evening was not answered.
Miklosi is challenging incumbent Republican congressman Mike Coffman in the redrawn and more competitive 6th Congressional District.
"This is another attempt to distract from the extreme Coffman-Ryan plan to end Medicare as we know it that is on everyone's mind," the Miklosi campaign said in a statement. "This election should be about the issues that affect people's lives and not about cheap personal attacks."
