NBC News presidential historian says Donald Trump's latest actions against special counsel Robert Mueller could be "ten times worse" than the obstruction of justice following Watergate that helped end the administration of President Richard Nixon.

Michael Beschloss, the author of the new book Presidents of War, joined MSNBC's "The Beat with Ari Melber" on Wednesday to discuss Trump ousting Attorney General Jeff Sessions and installing loyalist Matthew Whitaker.

Many believe the actions constituted obstruction of justice.

"Firing of Jeff Sessions -- replaced by what looks like a loyalist, who is on the record for narrowing in this probe -- where does this rate in comparison to Nixon," Melber asked.

"Ari, if this is going the way this looks, this is ten times worse than Nixon because, let's look, if this leads to let's say the firing of Robert Mueller or the substantial limiting of this investigation -- ten times worse than Nixon," Beschloss replied.

The historian described acting Attorney General Matt Whitaker as, "by most accounts, not terribly qualified -- by some accounts a political hack -- by almost all accounts, someone who can be relied upon to be completely obedient to President Trump."

"The case we're dealing with is a possible covert relationship between an American president and a hostile foreign power," Beschloss reminded. "That's way beyond Watergate."
