Today on NBC's Meet The Press, Newt Gingrich became the latest conservative to revive the oft-debunked falsehood that President Barack Obama voted as a state legislator to allow doctors to “kill babies.” Neither Meet The Press host David Gregory nor the other members of the panel pushed back on this offensive smear.

Gingrich criticized Republican leaders for calling for Rep. Todd Akin to drop out of the Missouri Senate race for comments he made about “legitimate rape” and abortion. In defending Akin, Gingrich claimed that Obama holds the truly extreme position because he voted to allow doctors to “kill babies”:

NEWT GINGRICH: The President of the United States voted three times to protect the right of doctors to kill babies who came out of an abortion still alive.

Gregory did not push back on this claim even though it has been widely debunked. The Associated Press noted in a fact check of a previous attempt by Gingrich to push this claim that Illinois law already required that doctors to provide medical attention if a live birth resulted from a botched abortion on a viable fetus:

As an Illinois state senator, Obama voted against legislation promoted by anti-abortion activists that would have conferred protection to fetuses showing any signs of life after an abortion, even if doctors did not believe the fetus was viable. Obama pointed to an existing Illinois law requiring doctors to protect fetuses they believed were likely to survive after an abortion, and said he was concerned the proposed new law was so broad it could interfere with routine abortions.

Politifact has rated similar claims “pants on fire” and The Washington Post's Fact Checker previously concluded that it is “unfair to accuse Obama of supporting the withdrawal of medical treatment from babies born as the result of a botched abortion.”
