Meg Whitman is slamming Chris Christie’s endorsement of Donald TrumpDonald John TrumpDems win from coast to coast Falwell after Gillespie loss: 'DC should annex' Northern Virginia Dems see gains in Virginia's House of Delegates MORE’s White House bid as an “astonishing display of political opportunism” and calling on Christie’s donors to reject Trump, according to NBC News.

The Hewlett-Packard CEO, who served as national finance co-chair of Christie’s now-suspended presidential campaign, said in a statement that Trump is “unfit to be President,” the network reported.

"He is a dishonest demagogue who plays to our worst fears. Trump would take America on a dangerous journey,” she added. “Christie knows all that and indicated as much many times publicly.”

Whitman said the New Jersey governor is mistaken if he believes he can still count on her support.

“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,” she said.

Christie endorsed Trump for president on Friday in a surprise announcement, telling voters that no one is better prepared to lead the country than the GOP front-runner.

“I’ve been on that stage, I’ve gotten to know all the people on that stage. And there is no one better prepared to provide America with the strong leadership that it needs both at home and around the world than Donald Trump,” Christie said at a joint press appearance in Texas alongside Trump.
