A second person has pleaded guilty in connection with a scheme to defraud a Minnesota Medicaid program for children with autism. So far the feds have charged 15 people in the Medicaid cases that prompted President Donald Trump’s administration to block $260 million in funding to Minnesota.

Minnesota is suing the Trump Administration in an attempt to stop it from withholding $243 million of that Medicaid spending. The lawsuit filed Monday asks a U.S. court in Minneapolis to issue a temporary restraining order to block the withholding.
