The U.S. Supreme Court has once again blocked Missouri from using a congressional map supported by former President Donald Trump. The ruling, issued Thursday, means the state cannot implement the maps that were favored by Republicans and had gained support from Trump.

This is the second time the nation's highest court has intervened to prevent the implementation of these specific maps. The decision comes amid a contentious legal battle over redistricting in the state, shortly before ballots are to be distributed for the upcoming November elections. The Missouri Supreme Court had previously cleared the way for the old maps to be used, but the state's primary election was already conducted using the newly contested maps.

A contempt hearing for Denny Hoskins, a state official involved in the redistricting process, is scheduled for this week. The Supreme Court's intervention adds another layer of complexity to the ongoing dispute over how Missouri's congressional districts are drawn.
