Donald Trump demanded Monday that Comcast launch an investigation into MSNBC host Joe Scarborough, pointing to a 2001 incident when one of his congressional interns died after falling at his Florida field office.

'Concast' should open up a long overdue Florida Cold Case against Psycho Joe Scarborough,' the president urged in a Monday morning tweet.

'I know him and Crazy Mika well, used them beautifully in the last Election, dumped them nicely, and will state on the record that he is 'nuts'. Besides, bad ratings! #OPENJOECOLDCASE,' Trump continued, referencing Scarborough's co-host and wife Mika Brzezinksi.

Scarborough responded to the tweet on Morning Joe Monday, calling for Vice President Mike Pence to take over authority for the time being, because he claims Trump is 'not well.'

'This president, I ask that you get checked out. I ask that you take a rest, I ask that you take care of yourself. Maybe let Mike Pence run things for the next week,' Scarborough said.

'You're not well. Let Mike Pence work with Michael Fauci, work with Dr. Birz. It would be best for you politically. It would be best for the country medically. It would be best for the Republican Party politically. Talk about social distancing, we're reading stories now about republicans who are politically distancing from you,' he continued, referencing the president's response to the coronavirus outbreak.

Lori Klausutis was an intern in Scarborough's congressional field office in Florida when he was a Republican congressman for the state. In 2001 she fell and hit her head while in the office and died from complications. It was later found she had an undiagnosed arrhythmia and Scarborough was out of town at the time of the incident

The president is demanding Scarborough's employer, Comcast, look into the situation surrounding Lori Klausutis' death. Comcast owns NBCUniversal Media, which includes NBC News and MSNBC.

Klausutis died in 2001 at age 28 while she was an intern for Scarborough after falling and hitting her head at his Florida district office.

Local authorities later revealed that Klausutis had an undiagnosed heart condition that led to the complications that led to her death, and the official cause of death was attributed to an arrhythmia.

An immediate investigation found no evidence of foul play, adding that Scarborough was out of town at the time of the accident and her death.

'You actually tweeted something extraordinary cruel,' Scarborough charged of the president's Monday morning tweet. 'And I know you meant to be extraordinarily cruel to me, by attacking me. By bringing up a conspiracy theory that has lived in the gutters of the internet for some time now'

'You don't understand the pain you cause – you cause the families who've already lost a loved one. Not me. Not my children. Not anybody that knows me or – they know the truth. But, you once again drag a family through this, and make them relive it again,' he continued. 'As if losing a loved one the first time isn't enough.'

He also lamented about the president's 'working weekend' at Camp David, claiming the instead of working to help with mitigation for the coronavirus pandemic, he tweeted hate toward the media, conspiracy theories and an attack against George W. Bush.

'But this weekend, my God, you were supposed to have a working weekend. You got it wrong again,' Scarborough said.

The president has referenced the case about Klausutis in the past, when just over a year after Trump was elected he questioned if the 'unsolved mystery' would ever be reinvestigated when talking about other media scandals.

'So now that Matt Lauer is gone when will the Fake News practitioners at NBC be terminating the contract of Phil Griffin? And will they terminate low ratings Joe Scarborough based on the 'unsolved mystery' that took place in Florida years ago? Investigate!' he tweeted in November 2017, referencing Scarborough and MSNBC President Phil Griffin.

Scarborough and his wife and co-host Mike Brzezinski also slammed Trump for his 'working weekend' claiming that instead he spent his time at Camp David spreading conspiracy theories and bashing journalists

The morning after the tweet, the two responded to the tweet by Brzezinksi reading a statement on behalf of Scarborough, who repeatedly refused at the time to directly respond to any personal attacks from the president on Twitter.

'The president was tweeting yesterday, among other things, the conspiracy theory about Joe being a murderer,' Brzezinski read on Morning Joe at the time.

'Today the president crossed another deeply disturbing line with his attack on Joe. The chief law enforcement officer of the United States of America advanced a false conspiracy theory to intimidate the press and cause a chilling effect on the First Amendment,' she continued. 'Joe and I are not intimidated. His bizarre behavior contravenes both the Constitution and basic moral judgment. This is all we're going to say on the matter.'

Trump's personal attack on the morning show host and former Republican Florida congressman is no surprise as he has often lashed out at the liberal duo.

He claimed during a tweet storm in June 2017 that Brzezinski showed up to a New Years Eve gathering at his Mar-a-Lago resort in Florida 'bleeding badly from a face-lift.'
