Don Lemon put his foot in his mouth on CNN's morning show again on Wednesday during a segment about presidential candidate Nikki Haley's idea to require mental competency tests for elected officials over the age of 75.
Lemon told his female co-hosts that she should be careful making comments like that about older politicians because she's "isn't in her prime" at 51 years old.
Poppy Harlow pushed back on his comments and he later apologized.
