A Michigan man is challenging the bailout of American International Group Inc., claiming it is illegal because the insurer has financial products that promote Islam and are anti-Christian.

The lawsuit was filed Monday in federal court in Detroit by the Thomas More Law Center, which pursues cases on behalf of Christian causes.

The lawsuit says AIG offers financial services that comply with Sharia principles. It says the government is violating the Establishment Clause of the First Amendment with billions of dollars of aid for AIG.

The clause prevents the U.S. government from endorsing a religion.

The lawsuit was filed on behalf of Kevin Murray of Washtenaw County, an Iraq War veteran. A messaging seeking comment was left with the Treasury Department.
