Republicans who control the Michigan Legislature have spent about $542,000 suing Democratic Gov. Gretchen Whitmer over her use of emergency powers during the coronavirus pandemic.
The Senate and House released the figure to a liberal group, Progress Michigan, last week.
It was the same day the state Supreme Court ruled against the governor in a similar lawsuit to the Legislature's.
The Whitmer administration has quickly reinstituted a mask requirement and gathering limits under a law that's not an issue in the legal challenges.
The $542,000 of public money has paid attorneys at Bush Seyferth, a Troy-based law firm.
