After being reelected unopposed in 2010, Murray was appointed chair of the Ways & Means Committee for 2011–12. Murray previously served as chair of the House Transportation Committee. He was also active in advancing LGBT rights. He led the push for an anti-discrimination law barring businesses from discriminating against gays and lesbians, a measure that finally passed in 2006 after three decades of debate. He was also the main sponsor of legislation creating domestic partnerships, approved in 2007. In 2009, Murray was the prime sponsor of a $2.4 billion Washington Senate financing bill authorizing the construction of a deep-bore tunnel underneath Seattle to replace the Alaskan Way Viaduct. Murray advocated for the project, which attracted well-documented concerns. Bertha, the machine drilling the deep-bore tunnel, broke down in December 2013, leading to costly delays and significant challenges such as destabilizing soil conditions under Seattle's historic Pioneer Square and the Viaduct itself. As of mid-2018, cost overruns on the tunnel project exceed $600 million. Mayoral career Murray was elected mayor of Seattle in 2013. He ran for reelection in 2017, but ended his campaign on May 9 amid allegations of child sexual abuse. On September 12, 2017, amid more sexual abuse claims, Murray announced his resignation effective the next day. Personal life Murray is of Irish descent. He is gay, and came out in 1980.

Murray did not emphasize his sexual orientation during his career, describing himself as "a Democrat who happens to be gay." During his campaign for the Senate, as in many of his previous campaigns, he won the backing of the Gay & Lesbian Victory Fund. Child sexual abuse allegations Five people have accused Murray of sexual abuse. In April 2017, a lawsuit claimed that he "raped and molested" a teenager in 1986, paying cash for sex to a high-school dropout addicted to crack cocaine. Two other men made similar allegations in 2007, including a foster son who said Murray sexually assaulted him in 1984 while he was a teenager. He had spoken with a child welfare investigator and detective at the time, and persuaded the investigator that Murray had sexually abused him, but no charges were filed. Through a spokesman, Murray denied the allegations, describing them as falsehoods intended to prevent his reelection. Later, Murray's lawyer said
