Mayor Michael Bloomberg asked others to join the call for marriage equality at the launch of the Freedom to Marry campaign in Washington, D.C, on Friday.
In prepared remarks, Bloomberg said an average of 700 gay couples get married in New York City each month, and said the state was able to legalize same-sex marriage last year by bringing Democrats and Republicans together.
“As the mayor of the largest city in the largest state in the union to have guaranteed marriage equality, let me tell you: The freedom to marry has only made New York stronger," Bloomberg said.
Bloomberg, along with 70 other mayors, launched the Freedom to Marry group at the U.S. Conference of Mayors meeting. Supporters include the mayors of Boston, Houston, Los Angeles and San Diego.
Bloomberg will co-chair the group.
