New Jersey Gov. Chris Christie (R) on Sunday said that it is a “normal step” for special counsel Robert Mueller to impanel a grand jury as he investigates Russian election meddling and any possible ties between President TrumpDonald John TrumpHouse Democrat slams Donald Trump Jr. for ‘serious case of amnesia’ after testimony Skier Lindsey Vonn: I don’t want to represent Trump at Olympics Poll: 4 in 10 Republicans think senior Trump advisers had improper dealings with Russia MORE's campaign staff and Moscow.

“The coverage about how monumental this was is just a fundamental misunderstanding of the way this process works,” Christie told CNN’s “State of the Union.”

Christie said the grand jury is a “normal step taken by a careful prosecutor” and a “typical thing to be done in any investigation.”

“You can’t issue subpoenas without a grand jury. It’s the grand jury that actually issues subpoenas.” Christie said.

Christie, a Trump ally who endorsed the billionaire during the GOP primaries, defended Trump, saying there is no evidence of collusion between the president's campaign and the Kremlin.

“There is absolutely no evidence of any collusion at all between the Trump campaign and the Russians,” he said.

“Everybody in retrospect knows this was a bad idea,” Christie told host Jake Tapper.

The governor said he believes Trump is telling the truth and that the special counsel should continue its probe and “let the chips fall where they may.”
