HOC meaning in Governmental ?

The Committee on Oversight and Reform is the main investigative committee of the United States House of Representatives.

The committee's broad jurisdiction and legislative authority make it one of the most influential and powerful panels in the House. Its chairman is one of only three in the House with the authority to issue subpoenas without a committee vote or consultation with the ranking member. However, in recent history, it has become practice to refrain from unilateral subpoenas.

Carolyn Maloney (D-New York) served as acting chair of the committee following the death of Elijah Cummings (D-Maryland) on October 17, 2019; she was elected chair a month later. Representative Jim Jordan served as ranking member from January 3, 2019, until March 12, 2020. On March 31, 2020, Jordan started his second stint as ranking member. Representative Mark Meadows served as ranking member from March 13, 2020, until March 30, 2020, when he resigned his congressional seat to become White House Chief of Staff. Representative James Comer (R-Kentucky) was selected to succeed Meadows on June 29, 2020.
