<p>Which bodies of the US government provide oversight of DHS Aviation Security functions?</p>

<p>The Department of Homeland Security is a cabinet-level arm of the Executive Branch. The Sec'y of Homeland Security directly "runs" that branch, and serves at the pleasure of the President of the United States. There is a <a href="https://en.wikipedia.org/wiki/United_States_House_Committee_on_Homeland_Security" rel="noreferrer">House committee</a> on Homeland Security which conducts "oversight" and handles legislation related to security. There is likewise a <a href="https://en.wikipedia.org/wiki/United_States_Senate_Committee_on_Homeland_Security_and_Governmental_Affairs" rel="noreferrer">Senate committee</a>. <a href="https://www.dhs.gov/aviation-security" rel="noreferrer">This</a> is the DHS page on aviation security; and <a href="https://www.congress.gov/congressional-report/115th-congress/house-report/226/1" rel="noreferrer">this is a house report</a> on TSA oversight, connected to <a href="https://www.congress.gov/bill/115th-congress/house-bill/1351/text" rel="noreferrer">this bill</a> which did not become law, but is on the topic as an example of what legislative oversight would mean. </p>
