Democratic presidential front-runner Joe Biden took a shot at Massachusetts Sen. Elizabeth Warren Friday at a fundraiser in Houston, alluding to Warren’s numerous campaign policy plans she has proposed.

According to a Biden campaign pool report, the former vice president, 76, told donors at the gathering, “We need more than plans. We need a president. We need someone who can execute a plan.” He added that it’s not “what you want to do, but what you can do.”
