Pressed on whether comments such as DiGenova’s could be met with legal action, Krebs replied: “We’re taking a look at all our available opportunities.”

DiGenova’s attack against Krebs came on a Monday episode of the “The Howie Carr Show,” during which he criticized the former director of the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency for concluding that the election was conducted securely.

“Anybody who thinks the election went well, like that idiot Krebs who used to be the head of cybersecurity,” DiGenova said, “that guy is a class-A moron. He should be drawn and quartered. Taken out at dawn and shot.”

Trump ousted Krebs last month after his agency, CISA, shared a statement issued by a group of federal officials, election supervisors and voting technology vendors — including a CISA representative — deeming the 2020 election to be the “most secure” in U.S. history.

In the days before his dismissal, Krebs had privately expressed that he expected to be fired by the White House because of his bid to debunk disinformation being spread, in large part, by Trump and other Republicans.

Asked Tuesday whether he worried about his own safety in the wake of DiGenova’s attack and others, Krebs said he was “not going to give them the benefit of knowing how I’m reacting to this. They can know that there are things coming, though.”
