OKLAHOMA CITY (AP) — The Oklahoma Senate has given final approval to new maps of the 48 Senate districts in a bipartisan vote, despite objections from some Democrats that the maps were drawn in secret with the help of a GOP political strategist.

The Republican-controlled Senate voted 38-6 on Friday for the bill containing the new district lines. The measure now heads to the House, where it's expected to pass before heading to the governor's desk.

All opposing votes came from Democrats, who argued they were shut out of the process and not shown the final product until two weeks ago.

Democratic Sen. Jim Wilson of Tahlequah complained: "A sober person could not draw this map."

Redistricting Chairman Sen. Clark Jolley says members had the opportunity to consult with staff on drawing the lines.
