Former Florida Governor Charlie Crist has applauded a judge's ruling striking down the state's ban on gay marriage.

On Friday, Judge Sarah Zabel of the Eleventh Judicial Circuit Court in Miami ordered Miami-Dade County to allow gay and lesbian couples to marry. Zabel stayed her order. The ruling is the second blow to the ban. Earlier this month, Monroe County Circuit Judge Luis Garcia declared the marriage ban unconstitutional. Florida Attorney General Pam Bondi has appealed both cases.

Crist filed an amicus brief in support of plaintiffs in the Miami-Dade case.

“I was proud to file a brief in this case, an important step in the fight for marriage equality,” he tweeted Friday to his more than 20,000 followers.

In a follow up tweet on Sunday, Crist messaged: “I believe that all people should be able to marry the person they love.”

Crist, who previously supported the ban and is currently campaigning for his old job as a Democrat, has cited the GOP's opposition to marriage equality as chief among his reasons for leaving the Republican Party.
