Texas Republicans are poised to redraw the state’s congressional map during a special session that starts Monday.

House Democrats are actively preparing for political trench warfare against the GOP in next year’s midterm battle, with talks taking shape behind the scenes to mount a counterattack against President Donald Trump’s aggressive play in Texas that aims to cement GOP control of Washington for the rest of his second term.

The governor eventually agreed to include redistricting on his special session agenda after discussing the matter with the president on a phone call.
