Michigan’s state Senate has approved a measure that would require notice when the governor leaves the state as Gov. Gretchen Whitmer’s trip to Florida continues to attract scrutiny.

Weeks after Whitmer took a private plane to visit her ailing father in Florida, which some argue violated federal tax law due to the trip receiving funding from nonprofit organization Michigan Transition 2019, the upper chamber in the Michigan state Legislature voted in a 20-16 party-line vote to approve Senate Bill 458, which states “an individual that assumes the powers and duties of the office of the governor … shall make a good-faith effort to deliver notice to” the Senate’s majority and minority leaders, the speaker of the House of Representatives, and the minority leader of the House.
