House Speaker Nancy Pelosi, D-Calif., warned Democrats at the Democratic National Committee's summer meeting in San Francisco, Calif., on Friday that they have to "be ready to take a punch" and "be ready to throw a punch for the children."

In her speech, Pelosi predicted a "tough election" in 2020 because "it’s about money" for President Trump and the Republican Party, saying, "They will put up any amount of money to protect their investments in degrading the environment, guns, and all of that."

"You’ve got to be ready to take a punch," Pelosi said. "And therefore, you have to be ready to throw a punch. For the children. Throw a punch for the children."
