WATCH: Ex-Watergate prosecutor reads former Trump campaign aide the riot act for defending attempt to derail Mueller

Appearing on MSNBC on Tuesday afternoon, a former Watergate prosecutor unloaded on a former Trump campaign official for defending the president for attempts to hamstring special Counsel Robert Mueller.

Attorney Nick Ackermann, a former assistant Watergate prosecutor explained that President Donald Trump's dictation of his son's statement about meeting with Russians associated with the Kremlin was a bald-faced attempt to derail Special Counsel Robert Mueller's investigation.

"I want to be clear what you're alleging," host Ari Melber asked. "You're saying, you're alleging, that this type of public misleading was actually designed to ultimately interfere with an ongoing proceeding?"

"Absolutely," Ackerman asserted. "All these people have appeared before Senate committees. One would expect Mueller would ask them if what they said was true. I guarantee you they will say it's true. If you look at Jared Kushner's statement that was a written statement provided to the Intelligence Committee, it pretty much parroted the same thing that we knew all along but all of it is very surgically designed to obstruct this investigation and to kick both of these individuals out of the soup."

"On a scale of one to ten that's pretty up bat-crap crazy," replied former Trump official Barry Bennett. "He knows the frame of mind of everyone involved? It's not worth a discussion."

"It is worth discussing," the former prosecutor replied.

"It's not a discussion. It's a crazy theory," Bennett shot back.

That was when Ackermann unloaded on Bennett.

"Donald Trump said he got rid of Comey because he wanted to stop the Russian investigation," Ackermann blurted as Bennett attempted to talk over him.

"On TV, to the Russian ambassador in the Oval Office," Ackermann lectured Bennett. "If ever there was corrupt intent to stop this investigation you've got it in spades here. You also have Donald Trump trying to force out his attorney general because he wants to put in a puppet to get rid of Mueller."

"What he knows by setting up these phony stories that he put together, that he's putting both of these individuals, both of his relatives, at risk because ultimately he doesn't know all the evidence," Ackermann continued. "All of this evidence is going to come out and it's going to contradict those statements. Time is not on his side. That's why Donald Trump has a razor focus to trying to get rid of Mueller as quick as possible."
