Members of a local LULAC chapter put up a sign near Everhart Road, saying Nueces Co. Republican Party Chair Jim Kaelin needs to step down.
The move comes after Kaelin shared a post on his personal Facebook page in May about the circumstances surrounding George Floyd's death.
Governor Greg Abbott, Nueces County democrats, and members of the local NAACP have also called on Kaelin to step down.
Kaelin hasn't responded to calls for a comment about the billboard, but he previously said he has no intention of stepping down.
The wording of the original post questions the circumstances surrounding the video in which Minneapolis police officer Derek Chavin's knee is seen on Floyd's neck during a May 25 arrest. It was uploaded to Kaelin's Facebook page May 29, and is no longer public on his page.
