Meanwhile, Trump on Wednesday boasted about his administration's response to past hurricanes, while also referencing his past feud with San Juan Mayor Carmen Yulin Cruz over storm relief efforts in Puerto Rico a year ago. As time went by it did not go up by much.
On Thursday, Mr Trump wrote in a pair of tweets that Democrats were attacking him "when I was successfully raising Billions of Dollars to help rebuild Puerto Rico". The government of Puerto Rico accepted these numbers, too, after many months in which the official death toll was listed at 64 people.
"Puerto Rico was, actually, our toughest one of all because it's an island, so you just - you can't truck things onto it". Hurricane Florence, a Category 4 storm, is expected to hit the Carolinas and Virginia as early as Thursday night with the potential for strong winds, a massive storm surge, and heavy rain.
Thousands of people died in the wake of the storm, according to a study commissioned by the Puerto Rican government.
While Trump declared the United States' response to the assistance of the people of Puerto Rico a success, the numbers show a dim reality of the situation. "The problem with Puerto Rico is their electric grid and their electric generating plant was dead before the storms ever hit", Trump told reporters.
But after visiting the island last September, Trump said that Puerto Ricans were fortunate that the storm did not yield a catastrophe akin to the havoc wreaked by Hurricane Katrina along the Gulf Coast.
Trump tweeted Wednesday that the incoming storm is "looking even bigger than anticipated", urging those in the hurricane's path to "get out of its way". After all, that storm's official death toll sits at almost 3,000.
And Long said FEMA had made changes to some of its priorities and procedures.
"My teams knew about it but first they will say, "no we cannot use them, ' months later water was no good for human consumption", he tweeted".
Trump's tweets - which came as a highly unsafe Hurricane Florence churned toward the Carolinas - brought an immediate rebuke from Democrats in Congress. "The Trump administration led us to believe they were helping when they weren't up to par, and they didn't allow other countries to help us".
A photographer said Tuesday that a stockpile of bottled water he saw on a tarmac in Puerto Rico a year ago was still there during a recent trip.
