OLYMPIA -- The House Judiciary Committee will hold a hearing on the two gun control initiatives likely to go on the ballot later this year.

Among the speakers supporting Initiative 594, which would expand background checks for most gun purchases, will be former Rep. Gabrielle Giffords and her husband, former astronaut Mark Kelly. Also on the agenda is Initiative 591, which would require a federal standard for expanding background checks before any changes could take effect in Washington. 

The hearing is expected to draw an overflow crowd, with additional seating in the House gallery, something that's usually reserved for hearings on the very big, very contentious issues. 

We'll be covering it live, via Twitter, with reports being filed here on Spin Control.
