Former President Barack Obama waded into the debate over redistricting in a zoom call with Texas House Democrats on Thursday, warning of a “systematic assault on democracy” spurred by Republican efforts to redraw congressional maps in Texas.

Former President Barack Obama on Thursday joined a virtual meeting with Texas House Democrats who left the state to deny Republicans the ability to pass newly drawn GOP-favorable congressional maps, cheering on their efforts and stressing their work comes at a critical time in the fight against partisan gerrymandering.

Lawmakers are now framing their ability to prevent new maps from passing during one special legislative session as a victory. But Republicans are poised to call another.
