Meg Whitman, the CEO of Hewlett-Packard who had an official role with Gov. Chris Christie’s now-suspended presidential campaign, called his endorsement of Trump “an astonishing display of political opportunism.”

Whitman served in the role of national finance co-chair for Christie’s campaign.

“Trump would take America on a dangerous journey. Christie knows all that and indicated as much many times publicly,” Whitman wrote in a statement.

Here’s her full statement:

“Chris Christie’s endorsement of Donald Trump is an astonishing display of political opportunism. Donald Trump is unfit to be President. He is a dishonest demagogue who plays to our worst fears. Trump would take America on a dangerous journey. Christie knows all that and indicated as much many times publicly. The Governor is mistaken if he believes he can now count on my support, and I call on Christie’s donors and supporters to reject the Governor and Donald Trump outright. I believe they will. For some of us, principle and country still matter.” - Meg Whitman

Whitman joins a chorus of conservative commentators who have called Christie’s move “irresponsible” and a “disgrace.”

Christie’s surprise endorsement of Trump came this past Friday during a press conference in Texas. During the presser Christie said the businessman is “rewriting the playbook of American politics.”
