The Al Smith Dinner has traditionally provided presidential candidates with the opportunity to playfully jab one another in the campaign’s final days, but Donald Trump and Hillary Clinton used the opportunity to launch attacks and attracted some boo-birds.

Trump took the microphone first and began by making light of his wife’s speech at the GOP convention and about Clinton’s alleged misdeeds as secretary of state.
