WASHINGTON (AP) — President Donald Trump said Tuesday that he is pushing Texas Republicans to redraw the state’s congressional maps to create more House seats favorable to his party, part of a broader effort to help the GOP retain control of the chamber in next year’s midterm elections.

There could be some other states we’re going to get another three, or four or five in addition. Texas would be the biggest one.” he said Tuesday.

The effort could help Republicans maintain control of Congress next year. But it may also leave incumbents vulnerable to new Democratic challenges.
