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.

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

President Donald Trump told Texas Republicans Tuesday the White House believes the GOP can flip as many as five US House seats as part of a Republican redistricting effort in the state, according to a source familiar with the call.
