Only days after an analysis at The Federalist revealed the FBI created an anti-Catholic memo that accused church faithful of being domestic terrorists because the "Washington regime" has no tolerance for those opposing its "pagan morality," a U.S. senator is fed up with the bureau's refusal to provide information.

It was John Daniel Davidson at The Federalist who explained the FBI claimed the memo against Catholics came from one office, but that wasn't true, as officials in Richmond, Virginia, Los Angeles, and Portland all contributed.

Now it is Sen. Chuck Grassley, R-Iowa, who is calling out the FBI for refusing to provide information about the scandal.

"Although FBI Director Christopher Wray testified to Congress that the anti-Catholic memo was 'a product by one field office,' public disclosures from the House Judiciary Committee have since revealed that two additional field offices contributed to the memo’s production. The FBI has failed to follow up on multiple senators’ requests for information, preventing Congress from thoroughly investigating the memo," Grassley explained.

"Director Wray needs to shoot straight with Congress and the American people by providing a full explanation about the origin of this outrageous memo and his congressional testimony," Grassley said. "My colleagues and I won’t allow the FBI to pull the wool over Congress’s eyes while public faith in the agency continues to erode."

Grassley was joined in his letter to Wray by Sens. James Lankford, R-Okla., Mike Lee, R-Utah, Ted Cruz, R-Texas, Marsha Blackburn, R-Tenn., Mike Braun, R-Ind., Josh Hawley, R-Mo., and Rick Scott, R-Fla.

They want an explanation for Wray's "misleading testimony to Congress."

"Targeting Americans because of their ideas or political affiliations is always wrong and an abuse of the FBI’s power, but it’s especially alarming when it threatens the fundamental rights guaranteed in our Constitution, including the free exercise of religion," the senators wrote.

The letter said the FBI's original threat to Catholics relied on "blatantly biased and discredited sources to tie Catholic Christians to violent extremism based largely on their conservative political views on issues like, 'abortion rights, immigration, affirmative action, and LGBTQ protections.'"

The letter noted the FBI has declined to provide "sufficient answers" to many questions on the scandal.

"Six months after the fact, information continues to reach Congress in trickles, member and staff inquiries are ignored, and the information that has come to light conflicts with the FBI’s original assurances that the report was limited in scope," the letter said.

So the letter demands an "immediate explanation with respect to your potentially misleading testimony before Congress, as well as a full explanation of information that came to light during the internal review. We also request that you explain the Bureau’s failure to produce the information we requested that did not rely upon completion of the FBI internal review."

Further, it seeks all documents that already have been given to the House.
