who is the cheif officer of the house
Chief Administrative Officer of the United States House of Representatives In 2007 then House Speaker Nancy Pelosi (D-Calif.) appointed Daniel P. Beard of Maryland as CAO. She tasked him to carrying out her Green the Capitol initiative, a move that would later prove not too popular with some Congressional Members. Beard also restructured divisions within CAO that handled such administrative functions as House payroll and benefits.[1][2]|-In July 2010 he handed the reins of the position over to Dan Strodel of Virginia, who prior to becoming CAO served as a senior adviser on the House Administration Committee. Strodel held the position until early 2014 when Ed Cassidy took over responsibilities. Cassidy retired from the position on December 31, 2015, and was replaced by Will Plaster. Plaster served as CAO until July 31, 2016. The current CAO, Phil Kiko, took office on August 1, 2016.
Sergeant at Arms of the United States House of Representatives Through custom and precedent, the Sergeant at Arms performs a number of protocol and ceremonial duties. Among these duties are to lead formal processions at ceremonies such as presidential inaugurations, joint sessions of Congress (such as the State of the Union address, prior to 2007), formal addresses to the Congress, greeting and escorting visiting foreign dignitaries, and to supervise congressional funeral arrangements. In this capacity, the Sergeant at Arms is most famous for announcing the arrival of the President, a responsibility that he took over from the Doorkeeper of the United States House of Representatives when the latter position was abolished in 1995. Custom dictates that he announce the arrival of the Supreme Court, the President's cabinet, and finally the President by saying, "Mister (or Madam) Speaker, the President of the United States!"
