Trump fired Krebs last month after the CISA released a statement that pushed back on the president's claims of voter fraud. Instead, CISA said, the 2020 election was "the most secure in history" and there was "no evidence that any voting system deleted or lost votes, changed votes, or was in any way compromised."
"Anybody who thinks the election went well, like that idiot Krebs who used to be the head of cybersecurity ... That guy is a class A moron. He should be drawn and quartered. Taken out at dawn and shot," diGenova said on the show.
Krebs reacted to diGenova's remarks on Tuesday. In an interview on the Today Show, Krebs said it was another example of "more dangerous language, more dangerous behavior."
"The way I look at it is that we are a nation of laws, and I plan to take advantage of those laws. I've got an exceptional team of lawyers that win in court and I think they're probably going to be busy," Krebs told Today's Savannah Guthrie.
When asked specifically whether Krebs was looking at legal action, he replied: "We're taking a look at all our available opportunities."
Since being fired, Krebs has called Trump and his lawyer's efforts an attempt to "undermine confidence in the election" and a way to "scare people." The president, meanwhile, called the remarks "ridiculous."
