After being accused for years of exploiting the 9/11 attacks, Rudy Giuliani was roundly mocked on Monday for doing the opposite.

As Talking Points Memo reported, Giuliani said during a Donald Trump campaign rally in Youngstown, Ohio on Monday that, “Under those 8 years, before Obama came along, we didn’t have any successful radical Islamic terrorist attack in the US. They all started when Clinton and Obama came into office.”

Footage of the remarks can be seen below.

However, even if Giuliani was apparently willing to forget that he was the mayor of New York City during the attacks, social media users were not, as seen below:

@KailiJoy I guess "Never Forget" is negotiable depending on party affiliation.

So #RudyGiuliani basically just said 9/11 never happened? @nycjim @KeithOlbermann @nickgillespie pic.twitter.com/5oYLHcBAAP

I think it is official, Giuliani is crazier than Drumpf. https://t.co/RPH52MMH8V

I think a plane flew into #RudyGiuliani's head.

Rudi Giuliani forgetting about 9/11 is the 9/11 of never forgetting.

Rudy Giuliani forgetting 9/11 is like Lynyrd Skynyrd denying 'Freebird' exists.

THEORY: The real Rudy Giuliani has been dead for years. The crazy guy with the cartoon veneers is a nefarious actor pic.twitter.com/GskfCqSWv7

Rudy Giuliani just said the Yankees didn't win any World Series after President Obama was elected. This is crazy.

Perhaps Giuliani has come to agree with @KatrinaPierson that 9/11 was an inside job.

Giuliani was also taken to task for strangely calling Trump’s running mate, Indiana Gov. Mike Pence (R) the governor of Ohio — instead of John Kasich, who refused to endorse Trump after losing to him in the GOP primary.

Giuliani also just claimed Mike Pence is the governor of Ohio.

Rudy, are you ok?

Giuliani, in Ohio, just delivered praise of Mike Pence. Tells crowd, "You know better than I do what a great governor he is of your state."
