Four Obama administration cabinet secretaries have voiced their support for gay marriage.

Secretaries Hilda Solis at Labor, Kathleen Sebelius at Health and Human Services, John Bryson at Commerce and Timothy Geithner at Treasury have joined Shaun Donovan at Housing and Urban Development and Arne Duncan at Education in publicly endorsing gay nuptials, gay glossy The Advocate reported.

“We are proud of our president's history-making support for the right to marry regardless of sexual orientation,” Solis said in a statement commemorating LGBT Pride month, “just as we are proud that he refuses to use taxpayer dollars to defend the Defense of Marriage Act.”

A Sebelius spokesman confirmed to the magazine that she is in favor.

Duncan endorsed such unions before President Barack Obama made his historic announcement.

Appearing on MSNBC's Morning Joe, Duncan was asked by Mark Halperin, “Do you believe that same sex men and women should be able to get legally married in the United States?”

After a brief pause, Duncan answered: “Yes. I do.”

In an interview last year with gay weekly Metro Weekly, Donovan said that passage of a gay marriage law in New York made him proud to be a New Yorker.
