On May 17, 2017, Leahy received what were seen as potentially sexist remarks from LaVar Ball on The Herd with Colin Cowherd. He never faced in Leahy's direction for the whole interview, apparently trying to talk only with Colin Cowherd on the other side of the studio. Ball argued with Leahy about whether or not Big Baller Brand should market to both men and women and when she asked him how many shoes he had already sold, he said, "Stay in your lane." During the segment, Leahy expressed that she believed Ball was disrespecting women, and he responded by calling her a "hater" for her previous criticism of his parenting. He also commented, "She scares me. I don't look over there because I'm scared of her. I'm thinking assault right now. Leave me alone." Later that day on The Herd, Leahy issued a response about her argument with Ball, saying, "So he was upset at me for what I said there, and that's completely fine. But you can't come at me and disrespect me and not look me in the eye and threaten me. That's just not OK." Ball, however, denied threatening her.
On November 20, 2017, Leahy criticized CNN for inviting Ball on the air to discuss his feud with US President Donald Trump.
