President Donald Trump said on Tuesday his administration was doing a "really good job" helping Puerto Rico recover from the devastation of Hurricane Maria despite complaints that federal aid has been too slow to reach the U.S. territory.

Trump agreed to boost federal disaster aid to the island, increasing funding to assist with debris removal and emergency protective measures. He promised to visit Puerto Rico and the U.S. Virgin Islands on Oct. 3.

Critics and some of Puerto Rico's 3.4 million residents accused the U.S. government of having been slower to respond with water, food and electric grid repairs than on the mainland, even though the island's people are U.S. citizens.
