TALLAHASSEE, Fla. (AP) - A Lee County social studies teacher and the state's main teachers union are filing a lawsuit to block a significant expansion of a private school voucher program.
    
The lawsuit filed Wednesday in a Leon County circuit court contends that state legislators violated a requirement that bills cover only one subject. The Republican-controlled Legislature attached the voucher expansion to an unrelated bill on the final day of the 2014 session. They took that step because a stand-alone bill failed to get enough votes.
    
The $300 million program currently in place served nearly 60,000 families this past year. But the new law would broaden the eligibility for receiving vouchers.
    
Sen. Andy Gardiner, R-Orlando, criticized the lawsuit since the new law also expands assistance to families with disabled children.
