Significant differences between Speaker Mike Johnson (R-La.) and Rep. Barry Loudermilk (R-Ga.) are leaving plans for a new House GOP probe into the Jan. 6 Capitol attack in limbo more than two months after it was announced, as the sides collide over a new select subcommittee’s scope and authority.

Loudermilk, who is supposed to chair the new panel that would be housed under the House Judiciary Committee, is asking for broad jurisdiction and autonomy to go wherever the investigation takes him.

“We're kind of in flux right now, trying to negotiate out some of the jurisdictions,” Loudermilk told me earlier this month. “I just need to continue on the way we were going before.”

Here is Loudermilk’s ask: The Georgia congressman wants to keep researching security posture and issues that Republicans have with the original Jan. 6 select committee, which House Democrats controlled from 2021 to 2022.

That would include being able to find more videos of depositions conducted by the original committee; pursuing missing documents he believes are at the Department of Homeland Security; and investigating the Metropolitan Police Department's operations.

And here is the Speaker’s counter: Plans drawn up by the Speaker’s office, I’m told, would limit Loudermilk’s jurisdiction to that of the House Judiciary Committee.

Loudermilk would still have the ability to dig into issues like the search for the suspect who planted pipe bombs, or trying to get more information from the FBI about informants in the crowd. (The Justice Department’s inspector general said there were no undercover agents at Jan. 6, but found 23 confidential human sources in connection with the rally.)

But this would close off areas of investigation into the Capitol’s security posture and the probes into the previous Democratic-run Jan. 6 panel.

Some of the delay is related to Johnson’s schedule. The Speaker has been busy trying to prevent a government shutdown and working on a framework to pass President Trump’s legislative agenda.

There is major interest in the panel from the inmate-turned-activist Jan. 6 defendants who got pardons or commutations from Trump — some of whom have already been communicating with Loudermilk’s office about information they want to share.

“I personally have spoken with [Loudermilk’s] office, and others........
