https://www.google.com/search?q=%22dead+intern%22+site%3Ademocraticunderground.com
You will get a hundreds of results suggesting that Joe Scarborough is culpable in the death of Lori Klausutis.
Ms. Klausitis was an intern who worked for then-Congressman Scarborough. She had a heart condition, had been complaining of not feeling well, and was found dead after working alone in his office. An investigation concluded that her condition caused her to lose consciouness, fall, and hit her head on a piece of furniture.
A number of DUers have steadfastly maintained for years - on the basis of no evidence whatsoever - that Ms. Klausutis was killed by Joe Scarborough, and that he managed to cover up her murder.
The remarkable part about the cover-up is that Ms. Klausutis' husband and parents were apparently in on it. Not once in the many years since her death have those closest to and most personally invested in Ms. Klausutis raised any suspicion whatsoever that her death was anything other than it was determined to be. Fortunately, total strangers on the internet care more about her than they do, and so they know "what really happened".
Nevertheless, the epithet "dead intern Joe" is a common one on DU, because for people who toss that around, she is not really a person, and her family and loved ones are not really people either. Her corpse is just a convenient prop to wave around when a person on TV says things we don't like.
