States can draw electoral maps for partisan gain, but not if it dilutes the power of voters of color, courts have found.

Democratic Rep. Jasmine Crockett said Friday that GOP-proposed congressional maps in Texas would draw her out of the district where she lives, part of a redistricting effort Democrats say is aimed at at picking up five seats to keep Republican control of the U.S. House of Representatives.

Democratic lawmakers tried to build a case Friday that Republicans in Texas have engineered a rushed and unfair process for redrawing the state's congressional districts in response to a push by President Donald Trump to win more GOP seats that Democrats fear will spread to other states.
