Story highlights Sanders contrasted Trump with the mayor of San Juan

The White House budget director said the administration is doing everything it can

Washington (CNN) Vermont Sen. Bernie Sanders on Sunday rebuked President Donald Trump's decision to attack the mayor of San Juan on Twitter as Puerto Rico continues to struggle after being hit by back-to-back hurricanes.

"It is unspeakable," Sanders told CNN's Jake Tapper on "State of the Union."

Sanders drew a contrast between Trump and San Juan Mayor Carmen Yulín Cruz, saying Trump was "speaking from his fancy golf club, playing golf with his billionaire friends, attacking the mayor of San Juan, who is struggling to bring electricity to the island, food to the island, water to the island, gas to the island."

Sanders also said it would be fair for people to wonder if race was a factor in Trump's response to the devastation in Puerto Rico.

"Given the President's history on race, given the fact that he, a few months ago told us that there were good people on both sides when neo-Nazis were marching in Charlottesville, yeah, I think we have a right to be suspect that he is treating the people of Puerto Rico in a different way than he has treated the people of Texas or Florida," Sanders said.
