Aides from over a dozen House offices secretly convened today on the Senate side of the Capitol at a meeting organized by Senator Jeff Sessions of Alabama, a top immigration hawk who has recently involved himself more aggressively in the affairs of the lower chamber.

“Over here in the Senate working for Senator Sessions, we learned a lot last year about the strategies employed by the powerful forces pushing bad immigration policies–and how to counter them,” reads a copy of the invitation to the meeting provided to Breitbart News by a House staffer.

Officials close to the matter say conservative critics of Speaker John Boehner’s planned immigration push are working to issue their own rival immigration principles to vie with the document Boehner is drafting.

“There is definitely a growing mood of confusion and aggravation among conservatives in the House over the immigration issue right now,” one House GOP aide said in an email to Breitbart News, adding that many on the right find the “political logic” of riling up the party’s base so close to a low-turnout midterm election baffling.
