During the vote on the emergency clause for Speaker Kris Steele's HB2139, which expanded the State Superintendent's authority and limited that of the State Board of Education (in response to the controversy over State Superintendent Janet Barresi's first school board meeting), several House members appeared to be purposefully absent. That's when State Rep. Jason Nelson (R-OKC) invoked House Rule 10.5, or the 'Call of the House'.
The procedural motion gives the House sergeant-at-arms the authority to "compel the attendance of the absent members."
After a roll call, the doors to the House chamber were locked, and the House sergeants began the search for missing Reps. John Bennett (R-Sallisaw), Mike Christian (R-OKC), Charles Key (R-OKC), Mike Reynolds (R-OKC), Mike Ritze (R-Broken Arrow) and Randy Terrill (R-Moore).
Peter J. Rudy of Oklahoma Watchdog has more on the story here, including the missing members on the second roll call.
UPDATE: Rudy got a response from Rep. Randy Terrill, one of the AWOL members. Read it here.
