Gov. Greg Abbott has threatened to remove 10 Democratic districts from Texas if California makes good on its threat to remove five Republican districts from its maps.

The battle over mid-decade redistricting in Texas -- where the state’s congressional lines could be redrawn well ahead of the upcoming census -- continues Monday.
