Mark DeSaulnier

On March 13, 2020, DeSaulnier was hospitalized in Washington, D.C., for a rib fracture sustained during a run, as well as for pneumonia. On March 21, it was announced that his health had declined, and he was reported as being in critical condition. He steadily recovered, and was released from the hospital on May 4.

In May 2019, DeSaulnier introduced the Bots Research Act (H.R. 2860), a bill to establish a task force of experts at the Federal Trade Commission to determine the impact of bots on social media, public discourse, and elections in the United States.

In May 2016, DeSaulnier announced that he had been diagnosed with chronic lymphocytic leukemia in 2015, and had undergone chemotherapy. While the cancer was described as incurable, DeSaulnier said he would still seek re-election.

In 2014, after George Miller announced his retirement from the U.S. House of Representatives, DeSaulnier announced his candidacy for California's 11th congressional district to succeed him. He won the general election in a landslide victory. DeSaulnier took office on January 3, 2015.

In November 2014, DeSaulnier was elected to represent California's 11th congressional district in the United States House of Representatives. As a result, DeSaulnier resigned his state senate seat in order to elevate to Congress.

In 2012, DeSaulnier proposed a bill, SB1366, that would require gun owners whose guns are stolen or lost report the fact to police within 48 hours. Failure to comply would result in fines on the first and second offenses, with higher fines and possible jail on the third. The bill was endorsed by the Brady Campaign to Prevent Gun Violence and the California Police Chiefs Association, and opposed by the California Rifle and Pistol Association.

The Contra Costa Times editorial board was critical of DeSaulnier's record as county supervisor. An editorial published in 2009 stated, "Many of the financial problems that afflict Contra Costa County today stem directly from decisions DeSaulnier championed while he was supervisor. Most notably, in 2002, at a time when the county faced a $31.5 million shortfall, was already laying off workers and was already experiencing increased public employee pension costs, DeSaulnier supported unsustainable pension increases that hiked benefits for public safety workers by as much as 50 percent. The plan allowed public safety workers to retire at age 50 with a pension worth 3 percent of their salary for each year served. Such excessive public employee union benefits have strained some local jurisdictions to the brink of bankruptcy."

In September 2009, DeSaulnier amended SB 88 to attempt to restrict the ability of local governments to shed pension programs through bankruptcy protection.

In 2009, DeSaulnier announced his candidacy for the United States House of Representatives in the special election in California's 10th congressional district after the resignation of the incumbent Ellen Tauscher, who endorsed him.

He received 98% of the vote in the June 2008 Democratic primary election against write-in candidates; former Assemblyman Joe Canciamilla initially was to challenge DeSaulnier for the Senate seat, but dropped out of the race. In the 2008 general election, DeSaulnier received 66.6% of the vote against Republican Christian Amsberry.

In the Assembly, DeSaulnier chaired the Committee on Transportation and the Select Committees on Growth Management and Air Quality. He was also a member of the Assembly Committees on Appropriations, Human Services, Rules and Labor and Employment. He authored or co-authored over 40 bills during the 2007–2008 legislative session.

In early 1994, Republican Governor Pete Wilson appointed DeSaulnier, then a fellow Republican, to the Contra Costa County Board of Supervisors district 4, filling a vacancy caused by the resignation of Supervisor Sunne McPeak. He was elected in 1994 and re-elected in 1998 and 2002. In June 1998, he received 98.4 percent of the vote against write-in candidates. In March 2002, DeSaulnier was reelected with 79 percent of the vote against challenger Dione Mustard.

Prior to serving in the U.S. House of Representatives, DeSaulnier was a member the Concord City Council (1991–1994), a Contra Costa County Supervisor (1994–2006), and a member of the California State Legislature, representing the 11th State Assembly district from 2006 to 2008 and the 7th State Senate district from 2008 to 2015.

DeSaulnier was appointed to the Concord Planning Commission in 1988. In 1991, he was elected to the Concord City Council and served as mayor of Concord in 1993. He was also a member of the University of California Toxic Substances Research and Teaching Program Advisory Committee.
