David Armijo Resigned From AC Transit Over Same Problem He Had At HART Florida David Armijo resigned from AC Transit in Oakland on March 25th and before the AC Transit Board could meet to fire him over accusations of brash behavior. AC Transit should have read the accounts of what led to his being fired by HART, the Hillsborough Area Regional Transit Authority, where he was CEO, in 2011. In reports David Armijo was described by whistleblower David Persaud as "Hostile and defensive with a nasty temper". On top of that Armijo's travel and expense record, and hiring practices and use of time were questioned. The HART Board grilled Armijo in the same way the AC Transit Board was about to before he jumped ship. So it's apparent that rather than face a déjà moment, Armijo said 'fuck it' and left AC Transit. The question is why did AC Transit ignore this?
