Tarrant county Republicans in Texas will vote Thursday on an effort by a faction to remove their vice chairman, Shahid Shafi, because he's Muslim.

Fort Worth is the largest city in Tarrant county.

The campaign against Shafi, a trauma surgeon and member of the Southlake City Council, was mounted by a small group of Republicans led by Dorrie O'Brien, a precinct chairman from Grand Prairie.

O’Brien writes on Facebook that she “never doubted” her side has the votes to remove Shafi from his post.

“We don’t think he’s suitable as a practicing Muslim to be vice chair because he’d be the representative for ALL Republicans in Tarrant County, and not ALL Republicans in Tarrant County think Islam is safe or acceptable, O'Brien wrote on Facebook, adding that "there are big questions surrounding exactly where Dr. Shafi’s loyalties lie, vis a vis Democrat and Republican policies.”

O’Brien says her effort to oust Shafi is not about his religion, but whether he supports Islam or is connected “to Islamic terror groups,” according to the Star-Telegram.
