In a little-noticed brief filed last summer, lawyers for the House of Representatives claimed that an SEC investigation of congressional insider trading should be blocked on principle, because lawmakers and their staff are constitutionally protected from such inquiries given the nature of their work.
The legal team led by Kerry W. Kircher, who was appointed House General Counsel by Speaker John Boehner in 2011, claimed that the insider trading probe violated the separation of powers between the legislative and executive branch.
