One day after his Abrupt Resignation from Nikola Corp., former Chairman and CEO Trevor Milton ghosted his Twitter followers and vanished from public view.

"The Nikola image is headed for the electric graveyard and its new chairman must reinforce confidence and prove to the public, and GM, that the company was not some giant fleece job and Investors were not the suckers who bought the fake watch on the streetcorner."

It is likely Milton was attracting ongoing negative commentary to his Twitter account, even if he wasn’t posting or otherwise interacting with users, and that is why he got off it, said Karl Brauer, executive analyst at iSeeCars.com and Forbes Autos Contributor.

That's in reference to a report that Holmes, the disgraced founder of fake blood-testing company Theranos, might argue that she was suffering from a "mental disease" when she allegedly defrauded investors out of hundreds of millions of dollars.

He said that with Girsky chairing the board and Mark Russell as Nikola's CEO and Kim Brady as its CFO, the communications and "narrative from management will set a more measured and less promotional tone with investors."

Given Milton's resignation and the federal investigations into Nikola, Girsky's first job is to "stay in the game and be transparent with the investors and keep engaging with GM with the plan.
