The Texas Senate approved a bill early on Saturday to redraw the state's congressional maps at the behest of President Donald Trump in an effort to flip five U.S. House seats held by Democrats to Republicans.

The lawsuit, filed on behalf of 13 Texas residents, states that the redrawn districts in the new map — which Gov. Greg Abbott says he’ll “swiftly” sign into law — are racially discriminatory and violate voter protection laws.

Democrats took to social media to to criticize the state's new congressional map after it passed the Texas Senate early Saturday morning, setting the path for Republicans to gain up to five additional seats in the U.S. House.
