Sen. Luther Strange and former Alabama Chief Justice Roy Moore spent Labor Day weekend trying to rally voters ahead of this month's critical GOP runoff for a U.S. Senate seat.

Strange and Moore face off in the Sept. 26 runoff in the race to fill the seat previously held by Attorney General Jeff Sessions.

Strange has been endorsed by President Donald Trump and a group linked to Senate Majority Leader Mitch McConnell.

However, Moore bested Strange by 25,000 votes in the primary.
