Once maps for their own districts were approved, House lawmakers moved quickly to certify maps for state Senate and congressional districts Thursday afternoon.

Unlike their Senate counterparts, House lawmakers added minor tweaks to the interim maps drawn by a district court in San Antonio.

Gov. Rick Perry instructed lawmakers to rubber stamp those maps, which were used in the 2012 primary elections, presumably to strengthen the state’s case before the Supreme Court. However, Rep. Drew Darby allowed minor tweaks to existing districts, sparking extended debate on the House floor.

The changes in House districts will still have to be reconciled with the Senate version, which was passed without alteration.
