Major News with Major Garrett: Great American State Fair; gas prices; Iran; SCOTUS surprises; health updates

CBS News Chief Washington Correspondent, joins John Hancock and Michael Kelley. Garret says the Great American State Fair on the National Mall has been, 'underwhelming and beset by some problems,' and, 'stumbled out of the gate.' Could we see a return to lower prices at the gas pump? Garrett notes that when oil prices go up, fuel prices climb pretty fast, like taking an elevator, but those same prices 'take the stairs, very gradually so,' when coming down.
