John Costello, a senior official for intelligence and security operations at the Department of Commerce, on Thursday announced his resignation in the wake of the riots at the U.S. Capitol.

“Today, I resigned my position as Deputy Assistant Secretary for Intelligence and Security at the Department of Commerce,” Costello wrote in a statement he tweeted

Following the rioters' breach at the Capitol, four people died and members of Congress were evacuated. 

“Yesterday’s events were an unprecedented attack on the core of our democracy—incited by a sitting president,” he wrote. “The president has long disregarded and diminished the rule of law and the constitution. Yesterday that culminated in violent sedition against the U.S. Congress for the purposes of overturning a legally recognized and valid election.”

Costello noted that “during my time in office, I strove to further cybersecurity and national security on behalf of the American people. I am sorry to leave that work unfinished, but yesterday’s events leave me no choice.”

Costello also serves on the Cyberspace Solarium Commission, a congressionally created group made up of members of Congress, federal officials and industry leaders that produced recommendations last year on how to secure the U.S. in cyberspace. 

He previously served as the director of Strategy, Policy and Plans at the predecessor agency to the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency. 

Costello’s resignation came on the heels of a flurry of other senior Trump administration officials choosing to step down following Wednesday’s events at the Capitol.
