PORTLAND — Maine author Stephen King and his wife have made what’s being called a “substantial donation” to a statewide group advocating for stricter gun control laws.

The Coalition for a Safer Maine says King is a gun owner and a defender of the Second Amendment who also supports expanded background checks on gun sales and a ban on the sale of high-capacity ammunition magazines.

The coalition says the contribution from King and his wife, fellow author Tabitha King, will be used to fund the group’s advocacy efforts. The Maine Legislature this week is considering several gun control bills.

After the Newtown, Conn., school shootings in December, King wrote a best-selling e-book titled “Guns” discussing his thoughts on gun control and gun rights.
