Texas Gov. Greg Abbott on Friday called a second special session to push through a redrawing of congressional maps to secure up to five more Republican seats in the US House.

Texas Republicans have ended a legislative session without approving new congressional maps but are ready for another to satisfy President Donald Trump’s wishes for redistricting that bolsters their party.

Democrats who run populous states are considering redistricting, but some of them face a hurdle: Their parties don’t have control over drawing legislative maps. Instead, the power is in the hands of independent commissions, something often left-leaning pro-democracy advocates have supported to enact fair maps that reduce gerrymandering.
