WASHINGTON D.C. (Metro) -- Brad Pitt is putting his money where his mouth is.
The Hollywood star and longtime advocate for same-sex marriages, has pledged to donate $100,000 to the Human Rights Campaign.
The gay rights group is working overtime to secure marriage equality in the final days of the election cycle.
In a statement, Pitt said he would double every dollar donated to supportive ballot initiatives -- in states like Maryland, Maine, Minnesota and Washington -- up to $100,000.
The actor says, "I'm not going to back down from the fight for loving and committed couples to have the ability to marry."
