Over the last 24 hours, former House Speaker Newt Gingrich has found himself back in the headlines. After Gingrich blamed liberal rhetoric for the shooting of Rep Steve Scalise on Wednesday, his latest tweet suggested a controversial conspiracy about Robert Mueller, which prompted one host on MSNBC take him to task.

Newt on Mueller

The never-ending saga surrounding Donald Trump and Russia continues after almost six months into the new administration. Despite denying the allegations on an almost routine basis, the former host of "The Apprentice" is facing daily an onslaught of criticism over the issue at hand.

In recent weeks, the scandal has involved the recent firing of James Comey as head of the FBI, who headed up testifying in front of Congress last week. Under oath, Comey accused Trump of lying about how he handled his exit from the bureau, while also claiming the president "defamed" him on the way out. With Comey out, fellow former FBI director Robert Mueller was tapped to be the special counsel to oversee the investigation into Russia. Mueller has been in the political cross-hairs of Trump and his supporters, with reports suggesting last week that the commander in chief was on the fence about firing him. On June 15, former Speaker of the House Newt Gingrich decided to give his thoughts on the situation, which didn't go over well with MSNBC host Joe Scarborough.

On Thursday morning, Newt Gingrich appeared to push a conspiracy about Robert Mueller being part of the so-called "deep state, a term recently used by those on the far-right.

"Muelleris now clearly the tip of the deep state spear aimed at destroying or at a minimum undermining and crippling the Trump presidency," Gingrich tweeted. Gingrich's tweet comes just one day after the news broke that Mueller was investigating the president for possible obstruction of justice.

Joe on Newt

Not long after Newt Gingrich accused Robert Mueller of being part of a "deep state" conspiracy, Joe Scarborough responded in a series of tweets.

"How dare you smear a man who served this country honorably for decades in both war and peace, winning the Bronze Star and Purple Heart," Scarborough tweeted back to Gingrich.

"Newt, whatever you think you're getting in return for obsequiously sliming an American hero, I guarantee you it's not worth it," Joe Scarborough went on to write, while adding, "Stop." Despite previously serving in the House of Representatives as a member of the GOP, Scarborough has been vocal in his opposition to the current administration, and has regularly hit back at those defending the president.

In his final tweet on the issue, the MSNBC host ripped the former Republican leader for pushing an unfounded claim less than 24 hours after the shooting of GOP Rep. Steve Scalise. "This is grotesque and fans the flames of rage among the unbalanced. What exactly is the price of an ambassadorship these days," he noted.
