Days after the deadliest act of terrorism on U.S. soil since 9/11, Donald Trump had a message for his legions of Twitter followers Friday morning: There's even more to come.

"People very unhappy with Crooked Hillary and Obama on JOBS and SAFETY! Biggest trade deficit in many years! More attacks will follow Orlando," Trump wrote. "MAKE AMERICA GREAT AGAIN! MAKE AMERICA SAFE AGAIN!" he tweeted minutes later.
