(CNN) The Democratic mayor of San Juan, Puerto Rico, slammed President Donald Trump on Thursday, telling Anderson Cooper that the White House's response to Hurricane Maria will go down in history as Trump's own Hurricane Katrina, a storm that many say marred George W. Bush's presidency.

"This is historic. It's a historic failing," said Carmen Yulin Cruz, speaking on CNN's " Anderson Cooper Full Circle ." "This is President Trump's Katrina."

"For a year he has tried to spin it," she added. "But the truth speaks louder than he ever will. He can spin it all he wants. Three thousand people died on his watch."

The mayor went on to criticize the Trump administration's response, calling it "structured negligence" that "allowed Puerto Ricans to die." She also described, in detail, the troubles that have plagued the island territory since the storm began a year ago.

"It is a monumental disaster. It is a historical failure and that is what the President is going to have to live with," she added.
