The Federalist's Sean Davis, quoting one of Biden's boosters, under the Twitter handle "Peter Vroom," made public what order the nuns were from. 

"The three nuns attending Trump's rally in Ohio today are from the order of the Children of Mary in Cincinnati, OH. Here's a comparison of their picture from the rally today without face masks and a picture from their website. I am not using their names," Vroom said. 

At the rally, the three nuns were front and center, behind the president's podium, with two holding rosaries and a third holding a bible.  

Twitter users noted the nuns were applauding throughout Trump's speech.
