Donald Trump today veered off his scripted remarks to briefly lie about where the Orlando shooter was born in an apparent effort to bolster his call for a ban on Muslims entering the country.

Trump gave a press conference Monday afternoon, aided by a teleprompter, at the Saint Anselm College in New Hampshire. Almost immediately, he suggested the suspected killer, Omar Mateen, could have been prevented from entering the country.

“The killer, whose name I will not use or ever say, was born in Afghan, of Afghan parents, who immigrated to the United States,” Trump said during a press conference Monday afternoon. “The only reason the killer was in America in the first place was because we allowed his family to come here.”

A compelling argument, but for the fact that Mateen was born in New York—just like Donald Trump.

So how did such a blatant lie make it into his scripted speech? Well, according to a copy of his remarks, Trump ad-libbed the line:

A good point—the only reason Donald Trump is in America is because we allowed his family to come here, too. Something to think about.
