A Texas mega-church has received backlash after it hosted a conservative rally where thousands of worshipers were filmed chanting 'Let's Go Brandon' on Saturday. 

Footage from inside the Cornerstone Church, in San Antonio, showed the congregants chant 'Let's Go Brandon,' which has become a conservative rallying cry that translates to 'F**k Joe Biden.'  

Church officials have said the chant did not occur during official services but rather during a 'ReAwaken America' conference where former Trump allies like Michael Flynn and My Pillow CEO Michael Lindell spoke, reported.   

'This past week, Cornerstone Church facilities were used by an outside organization. Cornerstone Church is not associated with this organization and does not endorse their views,' the church said in a statement.
