The group fighting to uphold the state's gay marriage law has reserved $5 million in television time, and statewide ads are expected to start running next month.

Zach Silk, a spokesman for Washington United for Marriage, says the group has reserved TV time "sometime after Labor Day" though he wouldn't specify an exact start date or how long the ad buy was for.

Referendum 74 asks voters to either approve or reject the law passed earlier this year allowing same-sex marriage in the state. That law is on hold pending the November vote.

Preserve Marriage Washington, which pushed to get the referendum on the ballot, has raised more than $471,000 in opposition to the law. Washington United for Marriage has raised more than $6 million.
