Lemon to Cupp: "Is it mommy brain?"

[CNN host Don] Lemon chose not to respond to this thought, but to rather keep harping on [S.E.] Cupp fumbling a statistic.

“Is it fair to say this because I’m not a mommy, but is it mommy brain?” he asked his guest.

Cupp appeared to be taken aback by the remark, resulting in a brief moment of awkward silence.

“No, Don, I just forgot what I was going to say,” she said.

“I forget what I’m talking about all the time,” Lemon said, soon breaking into laughter.

He later insisted, perhaps sensing the awkwardness following the “mommy brain” comment, “We’re not beating up on you. We’re just having fun.”
