Former New Jersey Gov. Chris Christie (R) has described President Trump as someone who is "undisciplined, immature and narcissistic" but not "stupid". He stated that while he feels the presidency is slipping away, he is not stupid. This statement was made during a live interview at Harvard University’s Kennedy School of Government. Christie also commented on the president's declining popularity among his core base and his net approval at 35 percent and 58 percent respectively. He attributed this to lawmakers and other leaders not holding Trump accountable for his actions.
