Mark A. Morgan (born 1965 or 1966) is an American law enforcement official who served as the Chief Operating Officer and acting Commissioner of U.S. Customs and Border Protection from July 5, 2019, to January 20, 2021.

While there, he was a member of the Eurasian Organized Crime Task Force, the Crisis Response Squad, and the Special Weapons and Tactics Team.

In 2014, Morgan served on a detail to U.S. Customs and Border Protection (CBP) in the Department of Homeland Security as the Acting Assistant Commissioner for Internal Affairs.

[1] Morgan was assigned to this position after the previous Assistant Commissioner, James F. Tomsheck, was removed for failing to investigate allegations of inappropriate use of force by border agents, and CBP head Gil Kerlikowske took the unusual step of requesting an interim appointment from outside the agency to pursue investigations more aggressively.

[5] On December 1, 2016, Morgan stated in a Senate hearing that he supported a comprehensive immigration overhaul, which was met with strenuous criticism from the National Border Patrol Council.

[8] In January 2019, Morgan said that he could determine if an unaccompanied minor would become a member of MS-13, a transnational crime gang known for gruesome violence, just by looking at their eyes.

[11] The Washington Post reported that the announcement "caught White House aides and Homeland Security officials by surprise.

[18] Since his appointment was never confirmed by the Senate and his tenure as acting commissioner exceeded 210 days, he can no longer legally lead the agency.

To circumvent the law, his new title is "Senior Official Performing the Duties of the Commissioner of U.S. Customs and Border Protection.

[22] Oregon Governor Kate Brown described the actions as "abuse of power," and accused DHS of "provoking confrontation for political purposes.

[26] Morgan defended the deployment of officers in military-style uniforms and using unmarked vehicles in a press conference on July 21, saying they had identifying numbers on their shoulders.

[26] In September 2020, Morgan made the unsubstantiated claim that "antifa" was sending organized protestors by plane to cities across the United States to incite violence.
