“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.
