President Obama openly mocked Florida Sen. Marco Rubio in his home state Thursday for condemning Donald Trump’s behavior, but saying he’ll vote for him anyway in November.

At a campaign stop in Miami, Obama noted that Rubio said the country “can’t afford” to trust Trump with the nuclear codes because he’s so “erratic.” Rubio, he said, also called Trump a “dangerous con artist who made a career out of sticking it to the working people.”
