"....The lowest price in the nation as of Friday was in Mississippi at $2.63 per gallon...."
That article should have said the lowest *average* price in the nation as of Friday was in Mississippi at $2.63 per gallon.

I did not see anywhere in my search where gas went below $2, as Trump claimed.

Thank you Lamplighter, Gasbuddy looks like a good resource for gas prices...I'll definitely be using it in the future.
