Chicago Mayor Rahm Emanuel on Friday applauded a federal judge's ruling allowing gay couples to begin marrying in Cook County, which includes Chicago, instead of waiting until June 1.

“I applaud today's decision that all Chicagoans have the right to marry,” Emanuel, a Democrat and long-time supporter of marriage equality, tweeted to his more than 78,000 followers. “Love does not discriminate, and neither should the law.”

“I look forward to the day where every American enjoys the same freedom to marry, and when our country can provide equal rights to everyone.”

Emanuel actively lobbied for passage of Illinois' marriage equality law, approved last year and set to take effect throughout the state on June 1.
