Meeting in Cleveland on Monday, Republican officials blocked an effort to soften the GOP's opposition to same-sex marriage.

The 112-member committee drafting the Republican Party's policy platform also overwhelmingly approved language in support of state laws that prohibit transgender people from using the bathroom of their choice.

In 2012, Republicans added language to the platform calling court rulings striking down state marriage bans “an assault on the foundations of our society.”

Billionaire Republican Paul E. Singer's group, the American Unity Fund, is leading the effort to tone down the platform's anti-LGBT rhetoric.

According to various reports, Singer has invested at least $5 million on the effort.

Rachel Hoff, who declared herself the committee's first openly gay member, offered the marriage resolution, which called for removing all the language in support of heterosexual marriage and replacing it with “respect for all families.”

Hoff emotionally told the committee that “freedom means freedom for everyone.”

Nearly 20 percent of the committee voted for Hoff's proposal.
