"They said, 'Tell all your FFL friends we're coming for them next,'" Mr. Fincher told The Epoch Times.

An ATF spokesman said he could not comment on the June 16, 2023, raid at Mr. Fincher's home in Tuskahoma, Oklahoma.

"We are not allowed to comment pertaining to ongoing investigations. I can assure you once we can discuss the case, you will be notified," Ashley N. Stephens, resident Agent in Charge of the ATF's Tulsa Field Office, wrote in an email to The Epoch Times.

According to Second Amendment advocacy groups, the raid indicates a coordinated effort by President Joe Biden's administration to throttle legal gun sales to advance a gun-control agenda.

Oklahoma state Rep. J.J. Humphrey is incensed over the raid.

He wrote to Oklahoma Gov. Kevin Stitt, Oklahoma Attorney General Gentner Drummond, and Pushmataha County Sheriff B.J. Hedgecock on Aug. 17, demanding an investigation.

Mr. Humphrey told The Epoch Times that there is a legal term for what the ATF did to get Mr. Fincher to give up his FFL.

"It's called extortion. The mob does it, criminals do it, and when you have a badge, that makes it worse," Mr. Humphrey said.

Mr. Stitt's office did not respond to emails or telephone calls seeking comment.

Spokespersons for the attorney general and Mr. Hedgecock said they are looking into the matter.
