House Republicans are preparing to reprimand Democratic lawmakers for their controversial “sit-in” protest over gun control, sources told POLITICO.

The exact language is still in flux, and multiple sources said discussions are ongoing. But Speaker Paul Ryan’s office and other leadership staff have been researching ways they can punish Democrats for their controversial occupation of the House floor to protest the chamber’s lack of response to the Orlando, Florida shooting massacre.

GOP lawmakers are expected to discuss the matter next week upon returning from their summer recess. While no votes have been scheduled, some members have been given notice that the response could come to the floor in September.

One option that’s been floated is a resolution broadly stating a sentiment that such tactics shouldn’t be allowed and will be sanctioned somehow going forward. Others are hoping Republicans will publicly rebuke certain Democrats they say “intimidated” nonpartisan House staff during the late-June incident.
