DONALD TRUMP HAS fired the head of the federal agency that vouched for the reliability of the 2020 presidential election.

Trump fired Christopher Krebs in a tweet, saying his recent statement defending the security of the election was “highly inaccurate”.

The firing of Krebs, a Trump appointee and director of the Cybersecurity and Infrastructure Security Agency, comes as Trump is refusing to recognise the victory of Joe Biden, and is removing high-level officials seen as insufficiently loyal.

He fired defence secretary Mark Esper on 9 November, part of a broader shake-up that put Trump loyalists in senior Pentagon positions.

Krebs, a former Microsoft executive, ran the agency, known as CISA, from its creation in the wake of Russian interference with the 2016 vote through to this month’s election.

He won bipartisan praise as CISA co-ordinated federal state and local efforts to defend electoral systems from foreign or domestic interference.

In recent days, Krebs has repeatedly pushed back against false claims that the election was tainted.

Earlier yesterday, he tweeted report citing 59 election security experts saying there is no credible evidence of computer fraud in the 2020 election outcome.

Krebs, from his personal Twitter account, replied to his sacking saying: “Honored to serve. We did it right. Defend Today, Secure Tomorrow.”

He closed with the phrase “Protect 2020,” which had been his agency’s slogan ahead of the election.

Officials with CISA and its parent agency, the Department of Homeland Security, had no immediate comment.
