Xavier Becerra, who had been the top Democrat on the House Social Security Subcommittee, has decided to leave Congress to become the California Attorney General. Becerra had served 12 terms in Congress and was Chairman of the House Democratic Causus. He had earlier announced his intention to become the ranking Democrat on the House Ways and Means Committee. He was thought of as a potential Speaker of the House and had been mentioned as a potential Vice Presidential candidate. Becerra has been an ardent supporter of Social Security.
John Larson of Connecticut is the second ranking Democrat on the House Social Security Subcommittee but that doesn't mean he will necessarily become the ranking minority member of the Subcommittee in the next Congress. Subcommittee membership is somewhat fluid. Larson could move to another Subcommittee or another more senior member of the Ways and Means Committee could move to the Social Security Subcommittee.
