The Arizona Independent Redistricting Commission has sent its congressional-district map to the U.S. Justice Department, according to a commission press release. The map was sent Thursday.

It will be reviewed by Justice, which has 60 days to do so before it accepts, rejects or seeks more information. Arizona's mapping process is subject to federal "preclearance" under the U.S. Voting Rights Act because of past voter discrimination issues in the state.

The redistricting commission staff continues to work on the legislative-district map, and there was no indication on when it will be sent to Washington.

Both maps were approved on 3-2 votes by the redistricting commission after a contentious series of meetings and political and legal maneuvers. Included at one point was Gov. Jan Brewer's call for removal of commission chair Colleen Mathis, which the state Senate voted for. But that action was overturned on appeal to the Arizona Supreme Court.

Moves are under way in the Legislature to seek repeal of the redistricting commission system. One such proposal, to replace it with a return to legislative drawing of maps, passed a Senate committee on Thursday. Any such move would have to go before Arizona voters for their approval.

A submission package includes the map itself, as well as supporting documentation about minority-voting strength, public participation and other aspects of the redistricting process.
