President Trump has canceled his trip to Poland as Hurricane Dorian is projected to bear down on Florida in the next few days. The president made the announcement Thursday at the White House during an event launching the U.S. Space Command.

"To ensure that all resources of the federal government are focused on the arriving storm I have decided to send our vice president, Mike Pence, to Poland this weekend in my place," the president said. "It's something very important for me to be here."

Mr. Trump said he would reschedule his Poland trip for some point in the not-so-distant future.
