The New York Times reports Whitman has signed a legal brief arguing gay people have a constitutional right to marriage. Whitman supported Proposition 8 during her campaign for governor in 2010. Other prominent Republicans who signed the brief include former presidential candidate Jon Huntsman, former New Jersey Governor Christine Todd Whitman and former Massachusetts Governors William Weld and Jane Swift.
The Supreme Court is set to hear arguments on whether Proposition 8 is constitutional next month.
