Turns out Booker did have something on his mind when he fired off the now-infamous look.

He told CNN’s Anderson Cooper:

“I just knew he had laid a gauntlet down and I was talking a little bit with (Julián) Castro. Both he and I knew, as people who can speak Spanish, that now we were gonna bring it as well.”

He said he didn’t quite remember what was on his mind but said he “realized that there’s a lot of bilingual people, some even trilingual, in this race, and I’m happy to have those skills.”
