Holmes' legal team says it isn't possible for him to get a fair trial in Arapahoe County. The prosecution, which says it will seek the death penalty against Holmes, objects to the motion.
Holmes is accused of fatally shooting 12 people inside a Colorado theater in July of 2012. He's facing 166 charges linked to the incident and has pleaded not guilty by reason of insanity.
A trial date is currently set for October 14.
