In final campaign stretch, Trump and surrogates attack Harris and mock Puerto Rico. Plus, the science behind hugs

Good morning.

Anger and vitriol took center stage at New York’s Madison Square Garden last night, as Donald Trump and a cabal of campaign surrogates held a rally marked by racist comments, coarse insults and dangerous threats about immigrants.

What were some of the most offensive remarks? One speaker described Puerto Rico, home to 3.2 million US citizens, as an “island of garbage”; Tucker Carlson mocked Kamala Harris’s racial identity; a radio host described Hillary Clinton as a “sick bastard”; and a crucifix-wielding childhood friend of Trump’s declared that Harris was “the antichrist”.

Puerto Rican stars back Harris. Bad Bunny and Ricky Martin threw their support behind Harris on the same same day that a comedian appearing at Trump’s rally made the offensive remarks about Puerto Rico. Martin posted on Instagram: “This is what they think of us. Vote for @kamalaharris.”
