A political novice in his own right, former New Jersey Gov.

Chris Christie has taken a shot at Republican front-runner Donald Trump, telling a group of donors at a dinner on Monday that the Republican nominee has not made a great deal of progress toward bringing about the sort of economic growth that’s needed to address the challenges facing Americans.

Christie, who served as Trump’s finance director and the governor of New Jersey, also told donors that he does not think that Trump has the right “track record” to be president, and that the real estate mogul “doesn’t have a clear idea of what he wants to do for the country.”

Christie was the only Republican candidate to enter the race for the GOP nomination last week and is now expected to enter next week’s primary contest with a clear lead over the other three.

But his remarks about Trump come as a growing number of economists, including some prominent Wall Street firms, have come to the opposite conclusion.

“I don’t think that we need to be afraid to disagree with the Trump team on things that they want to do,” said Michael P. Oreskes, who directs the Center for Economic and Policy Research at the University of California, Berkeley.

“I think we need some space to think about it.”

The comments, made during a lunch with some of the nation’s top venture capitalists, are the latest sign that the billionaire businessman has not earned support from those outside his own party who would like him to be the next leader of the free world.

Christie also said that he believes Trump has a “disconnect” from “his core supporters,” and that he would be a good pick as a vice president for Trump if he were elected president.

“If I’m president, I’ll go out and do everything that I can to make sure he gets re-elected,” Christie said.

“He’s the guy who got his name on the ballot.

I’d be glad to go out there and help him with the things that he wants done, and we’ll see what happens.”

While many Democrats have said that they do not plan to vote for Christie, many Republicans have said they are open to him if he becomes their vice president.

Trump’s name was among the names floated in recent weeks for a running mate, though the process has not yet begun.

The billionaire has also said he would appoint a special prosecutor to look into the Clinton Foundation, which is under scrutiny by the Justice Department.

On Sunday, Christie appeared on “Meet the Press,” the Sunday morning talk show hosted by CBS News anchor Chuck Todd, and said that the Clintons “have been extremely successful at the White House and they’ve had success at the foundation.”

“The foundation has not been a problem, I think that I would say,” he said.

In addition to Christie, former House Speaker Newt Gingrich and House Majority Leader Eric Cantor are among the other Republicans running for president.

The Democratic nominee for vice president is also expected to be announced soon.
