A U.S. Senate debate focused on social issues is scheduled for next month between the major Republican candidates.

The Alaska Family Council says the Aug. 4 debate will be held at a church in Eagle River.

The major Republican candidates in the race are Joe Miller, former state Natural Resources Commissioner Dan Sullivan and Lt. Gov. Mead Treadwell. The president of Alaska Family Action, in an email announcement Wednesday, said all three are expected to attend.

They are vying for the seat currently held by Democratic Sen. Mark Begich, who is seeking re-election.
