On Monday, Bill Donohue of the Catholic League told Fox News host Neil Cavuto that he was "suspicious" regarding the Notre Dame fire.

The Notre Dame Cathedral in Paris caught on fire. Authorities are still investigating the cause of the fire, and as of now, zero casualties have been reported.

"It's a monumental tragedy. Forgive me for being suspicious. Last month, a 17th-century church was set on fire in Paris. We've seen tabernacles knocked down, crosses torn down, and statues," Donohue said.

"We don't know that. If we can avoid what your suspicions are. Now I'm wondering how much more the Catholic Church commits to this or do you think they first want to get to the bottom of it?" Cavuto said.

"First, they have to get to the bottom of it. They will rebuild it. There's no question. I'm sorry. The Eucharist is being destroyed and excrement smeared on crosses," Donohue said.

"We cannot make conjectures about this. I'm sorry. Thanks very much. I do want to let people know, we're not trying to be rude to our guests. There's so much we don't know," Cavuto said.
