John Legend has joined the chorus of people slamming Pres. Trump for his harsh comments about Puerto Rico, which is still reeling from "apocalyptic" destruction unleashed by Hurricane Maria, which has knocked out power to the entire nation and caused catastrophic flooding and infrastructure damage. 

"POS POTUS insults Puerto Rico while they're going through a terrible humanitarian crisis," wrote Legend, in response to a Monday evening (Sept. 25) tweet from Trump in which he inexplicably took a shot at the nation by writing, "Texas & Florida are doing great but Puerto Rico, which was already suffering from broken infrastructure & massive debt, is in deep trouble."

The outspoken singer -- who was a vocal supporter of democratic presidential candidate Hillary Clinton -- joined Marc Anthony in rejecting Trump's criticism of the island, which is a U.S. commonwealth. "Do something about our people in need in #PuertoRico," tweeted Anthony, whose parents are from the island nation. "We are American citizens too."

Also chiming in and pleading with Trump to focus his energies on helping P.R., whose 3.4 million residents are facing months without power and cell service and possibly years of slow rebuilding, was Hamilton creator Lin-Manuel Miranda. The songwriter/singer has been encouraging his Twitter followers to donate to the Hispanic Federation, but when HuffPo writer Jennifer Bendery wrote on Monday that the White House was "expected to send disaster aid request to Congress 1st/2nd week of Oct for Puerto Rico," Miranda said that was too late.

In addition to Anthony and Jennifer Lopez -- who has pledged $1 million toward P.R. relief -- several other stars have spoken out about the need to support the country, including Jeffrey Wright, Rosie O'Donnell, Gina Rodriguez and Ricky Martin.
