Hoo boy.

Rep. Nancy Pelosi, the 78-year-old leader of the Democrats in the House, has been losing it for a while, but this one takes the cake (at least until the next blooper).

Pelosi was trying to criticize President Trump for his administration’s actions to secure the U.S.-Mexico border, while also claiming that Democrats have been stronger on border control.

“We have a responsibility to protect our borders. All of our borders. Let’s make no mistake about that. Democrats have been strong on that point. All of our borders,” Pelosi told the reporters in her weekly press conference.

“In fact, I said to some of you before, when we had the 9/11 incident and the commission was formed — and they made their recommendations — they made recommendations to protect America, but the Republicans would never take them up. And some of it was about our borders. The Republicans would never take them up,” she said.

That “incident” was the deadliest terror attack in the history of the United States.

Twitter jumped on the comment.
