“Trump” exclaimed, “Oh, my god, it’s her! The woman who was in charge of security on Jan. 6. It’s Nancy Pelosi!”

He added that women “should never run our economy. Women are terrible with money.”

“In fact, a woman I know recently asked me for $83 million,” he said, referencing the amount of monetary damages a New York civil jury recently awarded writer E. Jean Carroll…
