Jack Siepmann Joins Rep. Correa's Office as Senior Legislative Assistant

A Broad Portfolio in CA-46

Jack Siepmann is joining the office of Rep. J. Luis Correa (D-CA-46) as a senior legislative assistant, the latest move in a career that has taken him through several California Democratic offices.

Siepmann's role covers an expansive range of policy areas, including armed forces and national security, immigration, veterans affairs, health, crime and law enforcement, science and technology, and foreign trade, among others. Correa sits on the House Homeland Security Committee, the House Judiciary Committee, and the House Veterans' Affairs Committee, along with several subcommittees spanning border security, immigration enforcement, intellectual property and artificial intelligence, and veterans' health and economic opportunity.

On the legislative front, Correa's most advanced bill in the 119th Congress is the Emerging Innovative Border Technologies Act (H.R. 993), which passed the House in March 2025 with a 406-9 vote and was referred to the Senate Committee on Homeland Security and Governmental Affairs. The bill would require the Department of Homeland Security to develop a plan to deploy emerging technologies, including artificial intelligence, machine learning, and fiber-optic sensing, to improve border security operations.

Also in the pipeline is the CBP Canine Home Kenneling Pilot Act (H.R. 4057), which has been reported out of the Homeland Security Committee and placed on the Union Calendar. The bill would establish a pilot program allowing U.S. Customs and Border Protection canine handlers to house their working dogs at home rather than in centralized facilities.

On veterans issues, Correa has introduced the Innovative Therapies Centers of Excellence Act (H.R. 2623), which would direct the Department of Veterans Affairs to establish at least five research centers focused on emerging treatments for PTSD, depression, and substance use disorder, including psilocybin, ketamine, and MDMA. That bill is currently in subcommittee consideration.

Congressional Staff Background

Siepmann brings roughly four years of congressional experience to the CA-46 office, all of it within California Democratic offices. He began his Hill career as a staff assistant in the office of Rep. Mike Thompson (D-CA-4), serving from July 2022 through February 2024. He then moved to the office of Rep. Scott H. Peters (D-CA-50), where he held a series of roles, starting as a legislative correspondent from February 2024 to April 2025, then briefly serving as a legislative aide and communications aide before being elevated to legislative assistant, a position he held through May 2026.

Prior to his paid congressional work, Siepmann interned in the offices of the late Sen. Dianne Feinstein (D-CA) and Rep. Ami Bera (D-CA-6). He graduated summa cum laude from the University of California, Los Angeles, with a bachelor's degree in political science and government.

What's Ahead

The committees on which Correa sits have been active in the 119th Congress in several policy areas that Siepmann will be covering. The House Homeland Security Committee held a hearing in February 2026 on information sharing and security collaboration ahead of major events, and a separate markup session in September 2025 addressed DHS-related legislation covering cybersecurity and pipeline security. The House Judiciary Committee held a hearing in September 2025 on AI policy, examining whether a nationwide regulatory strategy was preferable to state-by-state approaches, and a December 2025 hearing focused on organized retail crime.

Correa has also been a visible presence on immigration oversight issues, joining colleagues in litigation against the Trump administration after it required advance notice before members of Congress could conduct oversight visits at ICE detention facilities. He has separately been outspoken about ICE enforcement operations in Orange County, arguing that raids were creating fear in communities and that federal agents' tactics were unconstitutional.

On the veterans front, Correa co-chairs the Psychedelic Assisted Therapy Caucus, which has focused on expanding access to psychedelic-assisted treatments for veterans dealing with PTSD and related conditions, an issue that directly relates to the Innovative Therapies Centers of Excellence Act he has sponsored.
