On Tuesday night, Harrison reposted an anti-Muslim video on his Facebook page. The video, created by an organization called Joined Hands Across America for Trump, shows purportedly Muslim children engaged in prayer and asks President Donald Trump to keep Islam out of America's public schools.
At Plano Mayor Harry LaRosiliere annual state of the city address Thursday night, he called for Harrison's resignation for the second time.
"We have policies that are clear about nondiscrimination so that everyone in our city really feels at home," LaRosiliere said, echoing his statements from a Wednesday afternoon news conference. "When that post came out, it was inappropriate, and it was not in line with who we are."
Harrison did not attend Thursday night's event, but his videotaped visage received a round of boos from the crowd when it appeared during a recorded message from the City Council that played before LaRosiliere's speech.

Harrison's opponents protested outside the theater where the mayor gave his state of the city address.

Harrison has not spoken with the media or appeared in public since his post went viral. In a statement posted to Facebook shortly after he deleted the video Wednesday, Harrison said that he isn't anti-Muslim.
"I want to sincerely apologize to the Plano Muslim Community for the unintentional hurt I caused by reposting something on my personal Facebook page that wrongfully implied I am anti-Muslim," Harrison wrote. "My intent on inputting this on my personal Facebook page was to emphasize that Christianity is not the only religion being targeted for exclusion in our public school. It was not meant as a personal attack against the Islamic faith."
