Missouri’s Attorney General Eric Schmitt has joined 10 other states pledging to support former President Donald Trump’s legal battle against the federal government surrounding documents seized from his Mar-A-Lago estate.

A brief filed Tuesday by 11 states in a federal appeals court backs Trump’s effort to appoint a “special master” to oversee the case.

It also opposes the Department of Justice’s attempt to use documents identified as classified as part of its criminal probe.
