George Stephanopoulos and Michele Bachmann Spar Over the Founding Fathers and Slavery (VIDEO)

Michele Bachmann has only been an officially-declared presidential candidate for 36 hours, but she's already on the defensive over her propensity for making controversial, factually dubious statements. Monday, the news cycle feasted after she gaffed by mistaking the home town of serial killer John Wayne Gacy for that of film legend John Wayne. Tuesday on 'Good Morning America' (weekdays, 7AM on ABC), George Stephanopoulos pressed her on a statement she made months ago that the founding fathers had "worked tirelessly to end slavery."

"You have the worst record of making false statements of any of the leading contenders," Stephanopoulos said. Challenging Bachmann on the statement concerning slavery, Stephanopoulos pointed out that many of the founding fathers, including Washington and Jefferson, were slaveholders.

Bachmann first responded evasively. "What our Constitution has done for our nation is to give us the basis of freedom unparalleled in the rest of the world," Bachmann replied. "That's what people want to get back to because they realize that our government is taking away our freedom."

Stephanopoulos tried to lead Bachmann back to commenting on her original statement regarding the founding fathers and slavery. In turn, Bachmann cited John Quincy Adams, son of founding father John Adams, as someone who did work to end slavery. Stephanopoulos countered that Quicy Adams' abolitionist work happened decades after the Revolutionary War and the creation of the Declaration of Independence and the Constitution, and that he was not himself a founding father.

Bachmann's response? She said although John Quincy Adams had been a young boy at the time, he was still "actively involved" in the Revolutionary War.
