McCain supposedly went to the mosque at the Masjid An-Nur Center in City Heights.
Ben Kalasho, president of the Chaldean American Chamber of Commerce, expressed his concerned over what role the mosque may have played in radicalizing McCain.
An official with the mosque, who wouldn’t go on camera, told Fox5 McCain didn’t attend regularly.
“Overtime they’re radicalized and that can happen at schools, it can happen in prisons, it can happen at mosques,” said FBI special agent Darrell Foxworth.
A multi-agency task force is constantly looking for leads and tips to prevent terrorist activity in San Diego, but Foxworth won’t confirm nor deny if they are in fact investigating this mosque.
The FBI is currently looking for another man fighting alongside terrorists who also lived in San Diego.
Jehad Mostafa is on the FBI’s most wanted terrorists list and is accused of aiding Somali terrorist organization Al-Shabaab.
Kalasho is calling on the local Muslim community to stand up and publicly condemn ISIS for its brutal killings of religious minorities in the Middle East.
“Where are the moderate Muslims? Why aren’t they publicly condemning ISIS?” Kalasho said.
