"Last Week Tonight with John Oliver." HBO On Sunday's "Last Week Tonight," John Oliver called out President Trump's response to the ongoing humanitarian crisis in Puerto Rico in the wake of Hurricane Maria.

After Trump took to Twitter on Saturday to bash the mayor of San Juan, Puerto Rico, for her "poor leadership" during the disaster, he faced widespread condemnation.

Oliver seized on what he called a "horribly racist" tweet from Trump, which suggested that "they," the people of Puerto Rico, "want everything to be done for them."

"Really? The primary obstacle to hurricane relief has been Puerto Rican laziness?" Oliver said. "You have got to hang it to Trump: anybody can say horribly racist things about Hispanic people on a golden escalator, but it takes real balls to do it while their fellow citizens are dying.

"Trump is basically saying, ‘When hurricanes hit our people, they’re not hitting our best. They’re killing poors; they’re killing lazies; and some, I assume, have said nice things about me."
