Virginia Democrats ask US supreme court to revive voter-approved electoral map

New voting maps flipped four Republican-held seats to give Democrats an edge in redistricting race sparked by Trump

Virginia Democrats asked the US supreme court on Monday to revive a congressional map designed to boost their party's chances in November's midterm elections, turning to the court as Republicans - including allies of Donald Trump - seek to preserve narrow control of Congress.

The case thrusts Virginia into an unusual, mid-decade redistricting showdown, as courts weigh whether lawmakers can remake House districts outside the normal post-census cycle - with control of a narrowly divided Congress potentially hanging in the balance.
