Two days after chef José Andrés released his book, We Fed an Island: The True Story of Rebuilding Puerto Rico, One Meal at a Time, President Donald Trump denied that an estimated 2,975 Puerto Rican American citizens died as a result of Hurricane Maria—a statistic that was reported by researchers at George Washington University’s Milken Institute School of Public Health.

Andrés’ book documents his experience serving food to the displaced during the aftermath of Hurricane Maria.

“Chef José Andrés arrived in Puerto Rico four days after Hurricane Maria ripped through the island,” Lin-Manuel Miranda and Luis A. Miranda Jr. wrote in the book’s forward. “For most people, there was no clean water, no food, no power, no gas, and no way to communicate with the outside world. Andrés addressed the humanitarian crisis the only way he knew how: by feeding people.”

Andrés, a proud Spanish-American, activist and founding chef of multiple Las Vegas restaurants, including Jaleo and Bazaar Meat, has strived to highlight the lives of immigrants and give back to communities. In 2010, Andrés founded the World Central Kitchen, a nonprofit that provides food to people in the wake of natural disasters, and in 2015, he withdrew from a contract to open a restaurant inside Washington, D.C.’s Trump International Hotel after Trump stated that Mexicans are criminals and rapists. Last week, Andrés told CNN that Trump should be ashamed about his recent remarks. “His tweet only showed his lack of empathy,” he said.
