The national finance co-chair of New Jersey Gov. Chris Christie’s suspended presidential campaign is lashing out at the governor for throwing his support behind GOP front-runner Donald Trump, calling the decision “an astonishing display of political opportunism.”

Meg Whitman, the president and chief executive officer of Hewlett Packard, says in a statement she will not be joining Christie on Trump’s campaign.

She says, “For some of us, principle and country still matter.”

Whitman adds that Trump is “unfit to be president” and “a dishonest demagogue who plays to our worst fears.

She’s calling on Christie’s donors and supporters to reject the newly-united pair.

But Christie is brushing off the statement.

He says in an interview on ABC’s “This Week” that the pair remain friends but disagree and “that’s OK.”

“Meg has always been free to express her views and I honor her,” he adds.
