Former CNN host Larry King has posed for a NOH8 photograph to raise awareness for marriage equality. He also filmed a soon-to-be-released advertisement calling on president Barack Obama to support the calls for gay marriage.

King is shown in the adverts with duct tape across his mouth and ‘NOH8′ written on his cheek. NOH8 is the name of the campaign against Proposition 8, which banned gay marriage in California.

Earlier this year, the NOH8 campaign wrote a letter to president Obama which has been signed by gay celebrities including Rufus Wainwright, Ellen and Portia DeGeneres and Glee star Jane Lynch, together with straight celebrity Martin Sheen and Marc Pincus, the chief executive of Zynga, the home of FarmVille and CityVille.
