Indiana Gov. Mitch Daniels says a bill he signed into law allowing people to bring their firearms to work is written in such a way that it may invite lawsuits.

The law, which takes effect July 1, lets workers keep guns locked out of sight in their vehicles while parked on their employers' property.

Daniels cited gun owners' rights under the Second Amendment and the Indiana Constitution and its broad support in the Legislature in signing the bill Thursday.

But he also said lawmakers might want to clean up "ambiguities" in the law that could invite lawsuits. He was referring to provisions exempting some employers including schools, child care centers, domestic violence shelters, and some utilities and chemical plants.

Opponents say the law could lead to workplace violence.
