Gov. Rick Snyder says the Republican-led Senate's decision to adjourn without voting on Medicaid expansion is unacceptable.
The GOP governor said Thursday the Senate should "take a vote, not a vacation."
Snyder cut short his trade trip to Israel to be back in Lansing lobbying for expansion, but the Senate didn't act and won't return for two months after adjourning later in the day.
Senate Majority Leader Randy Richardville said in a statement that the debate "is not over."
Snyder's problem is his fellow Republicans make up two-thirds of the Senate, and the GOP is more resistant to expanding the Medicaid program under the federal health care law.
Hospitals, insurers, small businesses and the poor are pushing the Senate to act, while conservative groups are pressuring senators to stand firm.
