Some disappointed activists say they are yanking their support for the Democratic Party after Senate Democrats opposed a proposal in an immigration bill that would have allowed citizens to bring their foreign-born, same-sex spouses to the United States.

Jonathan Lewis, a Miami philanthropist who donated more than $35,000 in 2012, has stopped giving and is urging others to do the same until President Barack Obama and his fellow Democrats stop breaking promises to the lesbian, gay, bisexual and transgender community.

“Now is the time to stop investing in Democratic cowardice and stand proud by withholding donations until we see our friends’ actions and deeds align with their rhetoric,” Lewis said in an email to Reuters.

“Pretty words about fairness and equality under the law from the president and Democrats in Congress do not absolve them from their moral duty to act,” he said.
