According to the Denver Post, a single bullet shattered the front window, and although there were people inside at the time of the shooting, no one was injured.
Denver police spokesperson, Raquel Lopez said police are looking for a particular vehicle, which may indicate that the shot was fired in a drive-by shooting.
Lopez told theshow on Friday night that there was no advanced threat against the Obama campaign headquarters and that there is an investigation underway.
President Obama has been the verbal and political target of right-wing radio, television and bloggers since taking the oath of office in 2009. It is unknown if the shooting at Obama's Denver campaign office was related to or inspired by an anti-Obama dissident.
