Barney Frank, the longtime Democratic congressman and leading liberal who brought new visibility to gay rights and crafted the most significant reforms to the financial system in a generation, has died. He was 86.Frank died late Tuesday, according to Jim Segel, Frank’s former campaign manager and close friend.Born in 1940 in Bayonne, New Jersey, Frank wrote in his 2015 memoir that he was drawn to public life after Emmett Till, a Black 14-year-old from Chicago, was lynched by white men in Mississippi. Frank would volunteer in Mississippi during the Freedom Summer of 1964, though he acknowledged his fast-talking style was a challenge in the Deep South.He entered politics in 1968 as an aide to Boston Mayor Kevin White before winning a seat in the Massachusetts House in 1972. Frank was elected to Congress in 1980, an otherwise dismal year for Democrats as the party lost dozens of seats in the U.S. House and Republican Ronald Reagan won the White House.Frank’s pragmatic style surfaced early in his congressional career. He joined the liberal Democratic Study Group to help push then-Speaker Tip O’Neill, D-Mass., to respond more aggressively to the Reagan administration. But Frank said he found himself more often agreeing with O’Neill’s less confrontational approach.Years later, as Congress prepared to pass a massive tax overhaul package, Frank intended to vote “no,” opposed to the bill’s lowering of top tax rates. He changed his mind, however, when he worked out a deal boosting affordable housing tax credits.“I was happy to sacrifice my ideological purity to improve legislation that was going to become law with or without me,” he wrote.Barney Frank was the House Financial Services Committee chairman in September 2008, when lawmakers had to find a legislative response to the financial crisis.Chip Somodevilla/Getty ImagesPresiding over a financial overhaulBy 2007, Frank was the chairman of the House Financial Services Committee, where he would leave his lasting policy mark as the U.S. economy careened toward collapse. He worked with the Republican Bush administration to pass a rescue package, providing vital support to financial institutions but spurring a populist revolt that still courses through American politics.Once the initial crisis eased, Frank helped develop the most significant reform legislation since the New Deal. Working with then-Senate Banking Committee Chairman Chris Dodd, D-Conn., the Dodd-Frank Act would enhance consumer protections, impose new capital requirements for banks and boost the ability of regulators to monitor risk.“Barney and I shared a fantastic relationship,” Dodd said. “I had many good moments in those 36 years in Congress, but none more significant, joyful, or productive than those almost two years working with Barney on our banking bill.”During President Donald Trump’s second term, his Republican administration has worked to roll back many of the legislation’s provisions, arguing they were too onerous.Frank faced his toughest reelection campaign in years in 2010 as the tea party wave swept over American politics. He opted against running again in 2012, though remained engaged in politics long after leaving Congress, including spending time as a contributor to the conservative Newsmax network.He remained a fierce critic of Trump. Asked for his prediction on who might succeed the president, Frank said, “unfortunately I won’t get to vote for it.”Watch a full-length 2018 interview between Marketplace’s David Brancaccio, Barney Frank, and Chris Dodd.More Marketplace coverage of the Dodd-Frank ActFrom April 2026: An Eddie Murphy comedy helped inspire the 2010 Dodd-Frank Act.
