On Monday, in an effort to buttress his support for gun control, former President Barack Obama reiterated the false claim that there have been 18 school shootings in 2018. According to The Washington Examiner, when Obama spoke to the audience at the interventional cardiology conference, aka CRT 2018, at the DAR Constitutional Hall, he intoned:

If you ask me the thing that broke my heart, particularly when now I see there have been, and I've gotta update this, [...] 18 shootings in schools this year... this year! And for the medical community, you see the statistics. The leading causes of death among young people in this country have all but, [car] traffic starts going down and stabilizing, gun-inflicted fatalities where you combine suicide and gun violence, it just keeps rising.

The claim that there have been 18 school shootings in 2018 was widely promulgated by gun control proponents after the Parkland, Florida massacre on Valentine’s Day; it was debunked soon after that, even by The Washington Post and Snopes.

Obama also claimed that he had wanted to institute changes in gun laws after the Sandy Hook shooting in 2012, but Congress prevented him from doing so. He neglected to mention that early in his presidency, from the day he took office until January 2011, the Democrats controlled both houses of Congress, and between August 2009 and January 2010, the Democrats had a supermajority in the Senate, giving them complete control of the government.

Obama stated:

Probably the thing that haunts me the most is the fact that after 20 six-year-olds were gunned down in the most brutal fashion possible, so much so that the police who found them had to get counseling and I had to spend hours with the parents after children they had sent off to school, almost toddlers, did not come home. Despite that, I could not get this Congress to move on anything, even the most modest approaches to reducing gun violence in our society. It was the worst day of my presidency. I've said it before. And the fact that we didn't try was shameful. It was embarrassing.
