Overview

  • Green will resign once the House passes President Trump’s reconciliation package, relinquishing his seat and Homeland Security chairmanship.
  • As committee chairman, he spearheaded Republicans’ impeachment of DHS Secretary Alejandro Mayorkas over -Mex-Mexico border policy.
  • He reversed a February 2024 decision to retire when President Trump urged him to stay and finalize border security measures.
  • Green said he has accepted a private sector position that prompted his decision to step down before his term ends.
  • His resignation will trigger a special election in Tennessee’s 7th District, likely preserving Republican control but potentially tightening the party’s narrow House majority.
