Barney Frank, the former U.S. congressman who became one of the first openly gay representatives, died on Tuesday at age 86, as reported by multiple U.S. media outlets. Frank had dedicated over three decades to serving southern Massachusetts in the House of Representatives, and recently, he was receiving hospice care at his home in Maine since April.

Remembered as a trailblazer for LGBTQ rights, Frank was the first member of Congress to enter into a same-sex marriage and played a significant role in restructuring financial regulations after the 2008 financial crisis.

He was, above all else, a wonderful brother. I was lucky to be his sister, said Frank’s sister, Doris Breay, to NBC Boston.

Frank informed those close to him about his hospice care, and his former campaign manager, Jim Segel, noted: He was certainly at peace with himself. He certainly left a mark and he was a leader on civil rights, on gay rights, on leading other marginalized communities.

His legislative contributions include the Dodd-Frank Act, named in part after him, which sought to create new regulatory bodies and implement stricter restrictions on banks following the Great Recession. He was also a strong advocate for ending discriminatory military policies and fought for laws to protect against workplace discrimination based on sexual orientation, although those efforts ultimately did not succeed.

As the nation mourns his loss, many reflect on Frank’s indelible impact on civil rights and financial policy in the United States. This breaking news story is being updated as more details emerge.
