According to RadarOnline.com, sources claim that Don Lemon's colleagues at CNN have been privately criticizing him for his "colossal ego" and suspect he may be planning to leave the network. Lemon, who was recently moved from his 10 P.M. primetime slot to co-host "CNN This Morning," has reportedly refused to take any responsibility for the network's plummeting ratings. Insiders have described Lemon as "moody" and unwilling to accept that the new CEO, Chris Licht, demoted him to a less prestigious position. As tensions continue to rise, sources allege that Lemon has been verbally aggressive toward his 30-year-old co-host Kaitlan Collins, as well as clashed on-air with Poppy Harlow. The source claims that Lemon is primarily looking out for his own interests and may be trying to find another job before the network potentially decides to let him go.
