Jeb Bush is going to bat for his beloved Houston Astros -- saying allegations they cheated during their 2017 World Series season is nothing more than "Fake news!"
"No way," Bush told us ... "Not the 'Stro Dogs! No way!"
"It's fake news!"
Bush -- who grew up in Texas and says he's a longtime Astros fan -- was smirking in our clip ... so it seems he knows the evidence is mounting against his squad.
In the past few weeks, videos have surfaced that seem to show the Astros used an array of visual signals and sounds to tip off batters about the types of pitches coming their way.
