Don Lemon's former co-hosts address his firing with well wishes.

Don Lemon's former CNN This Morning co-hosts, Poppy Harlow and Kaitlan Collins, addressed his firing during Tuesday's broadcast, wishing him the best and thanking him for his contributions. Lemon was let go from the network on Monday, which came as a surprise to staff. He had become the subject of controversy while co-hosting CNN This Morning, including making a remark about Nikki Haley's presidential bid. Lemon and former Fox News host Tucker Carlson have reportedly hired the same entertainment lawyer to negotiate their exits.
