According to Cyberscoop, Harrell wrote in his resignation letter, "During my time at [the Cybersecurity and Infrastructure Security Agency], we have responded to hurricanes and historic floods, provided expertise after mass-shootings, engaged thousands of critical infrastructure owners and operators, and we are now providing the private sector assistance during COVID-19.”
