Sarah Palin endorsement of Trump beneficial to her

• 2 killed, several homeless after early morning tornadoes hit Florida
• EMS worker dies of heart attack after responding to daughter's wreck
• Live shark found in Florida swimming pool
• Eagles guitarist Glenn Frey has died
• Gas prices plummet below $1 in some places
