Trump said Wednesday his federal officials are in Florida preparing for Hurricane Irma, which is expected to make landfall in South Florida on Sunday.

"Hurricane looks like largest ever recorded in the Atlantic!" Trump tweeted Wednesday morning. "Watching Hurricane closely. My team, which has done, and is doing, such a good job in Texas, is already in Florida. No rest for the weary!"

Trump issued a state of emergency declaration in Florida, Puerto Rico, and the U.S. Virgin Islands on Tuesday ahead of the Category 5 storm's landfall.
