May 12 (UPI) -- Missouri's Supreme Court has approved the state's new congressional maps, handing a win to the Trump administration as it seeks to create additional Republican-favored seats ahead of November's midterm elections.

The high court ruled unanimously Tuesday in three cases that challenged the map, stating in a joint opinion affecting two cases that the redraw does not violate the state's Constitution, and rejected a referendum-related challenge against the bill that permitted the unorthodox mid-decade redraw.

"Today's Missouri Supreme Court rulings are a HUGE victory for voters," Missouri Gov. Mike Kehoe, a Republican, said in a social media statement Tuesday.

"Missourians are more alike than we are different, and our Missouri Values -- rooted in common sense, hard work and personal responsibility -- are stronger and far more aligned across both sides of the aisle than the extreme left-wing agendas pushed in states like New York, California and Illinois.

"The Missouri First Map ensures those values are represented fairly and accurately at every level of government."
