Barney Frank, one of the first openly gay members of the United States Congress and a towering figure in American progressive politics, died on Tuesday at the age of 86 after spending his final weeks in hospice care at his home in Maine. A Democrat who represented southern Massachusetts in the House of Representatives from 1981 to 2013, Frank is best remembered as a co-architect of the Dodd-Frank Act — landmark legislation signed by President Barack Obama in 2010 that overhauled banking regulations in response to the 2008 global financial crisis. He was also a trailblazer for LGBT rights, becoming the first member of Congress to enter a same-sex marriage, and spent decades advocating for the repeal of discriminatory military and workplace policies affecting gay and lesbian Americans.
