Christopher Murphy has emerged as one of the Senate's most vocal advocates for gun safety legislation, rising to national prominence following his passionate 15-hour filibuster in 2016 demanding action on gun violence prevention. The Connecticut Democrat, who represents the state that experienced the devastating Sandy Hook Elementary School shooting, has made combating gun violence a defining mission of his career while also focusing extensively on healthcare policy and foreign affairs. Before joining the Senate in 2013, Murphy served three terms in the House of Representatives and began his political career in the Connecticut General Assembly at just 25 years old. Known for his progressive positions and willingness to challenge both parties when necessary, he has become a leading voice on issues ranging from mental health reform to U.S. involvement in overseas conflicts.
