Former GOP senator and presidential candidate Fred Thompson made a crack about gun control on Twitter Wednesday while referring to the recent discovery of an ancient hunting weapon in Wyoming.

Thompson, a frequent Twitter user, said:

10,000-year-old hunting weapon found near Yellowstone National Park. Next to it was a 10,000 year old Democrat trying to ban it. #ftrs #tcot

The tweet echoed Thompson's comment Monday about the Supreme Court's decision in the McDonald case to strike down Chicago's ban on individual gun ownership:

SCOTUS used 14th A. to apply 2nd A. to states & cities. First time I've ever seen liberals sad over an expansion of rights. #ftrs #tcot
