After taking the oath of office in 2001, Congressman Miller was appointed to the House Armed Services Committee and the Committee on Veterans’ Affairs. He quickly established himself within Washington as a strong advocate for veterans' concerns and immediately supported changes to concurrent receipt and policy changes such as a greater co-sharing between the military and veterans' clinics.

In 2009, Congressman Miller was appointed to the House Permanent Select Committee on Intelligence (HPSCI). The HPSCI provides policy guidance and sets classified funding levels for the sixteen agencies of the Intelligence Community funded by the National Intelligence Program and the Military Intelligence Program. Recently, the Intelligence Committee has held important hearings on the Foreign Intelligence Surveillance Act, U.S. Intelligence Operations against Al Qaeda, and Security Clearance Reform.

In 2011, Miller became the Chairman of the House Committee on Veterans' Affairs. The Committee on Veterans’ Affairs is responsible for authorization and oversight of the Department of Veterans Affairs (VA.) VA is the second largest department in the federal government with over 300,000 employees and a budget of over $119 billion.

Congressman Miller also serves on the North Atlantic Treaty Organization Parliamentary Assembly (NATO PA), where he serves as Vice Chairman of the subcommittee on Transatlantic Defense and Security Cooperation.

Since coming to Congress, Miller has established himself as one of the staunchest conservatives in the House. He has championed numerous tax relief and veterans' measures and fought for less government, less taxes, and more personal freedom.

Miller has appeared on the Fox News Channel, CNN, MSNBC, and ITN Television. He has been a guest on national radio programs such as G. Gordon Liddy Show and the Oliver North Show.
