California Gov. Gavin Newsom used his Democratic supermajority to push a new congressional map that favors Democrats in an effort to nullify the expected new map from Texas.

After Texas moved forward on a new Trump-backed congressional map this week, California Gov. Gavin Newsom responded, "It's on," moving forward on his own redistricting plan that favors Democrats.

If approved by voters, the California redistricting could nullify five new U.S. House seats Republicans are expected to gain from a new redistricting map in Texas.
