REVERE, Mass. (WBZ NewsRadio) — Two Muslim groups are demanding a full investigation into a Revere city councilor's online conduct.

Jetpac and the Council of American Islamic Relations, or CAIR-MA, said Revere City Councilor George Rotondo Jr. has been posting "Islamophobic and anti-immigrant propaganda" on his social media channels.

"These are [posts] in which he is sharing material from entities that the Southern Poverty Law Center has designated as anti-Muslim hate groups," CAIR-MA Executive Director John Robbins told WBZ NewsRadio's Suzanne Sausville.

The groups want the city to investigate whether or not Rotondo made the posts on the city's dime—"during times when he was being compensated for his labor by the city and its taxpayers, who include Muslim firefighters, Muslim physicians, Muslim attorneys, Muslim police officers and teachers," Robbins said.

The posts, which Jetpac screenshotted and are shown in the gallery above, include YouTube videos that claim Portland, Maine is "overrun with African migrants," a cartoon showing a Muslim man pulling puppet strings of a local political figure, and more.
