President Donald Trump suggested that he spent "a lot of time" with first responders after Sept. 11 as he signed an extension of the 9/11 Victim Compensation Fund.
"Many of those affected were firefighters, police officers, and other first responders. And I was down there also, but I’m not considering myself a first responder. But I was down there. I spent a lot of time down there with you," Trump said July 29 in the Rose Garden.
Trump’s comment, which appeared ad-libbed compared to the rest of his speech, didn’t go as far as some previous ones he made about his role in helping clear the rubble or supplying workers to help. But it still raised eyebrows. Some critics took his comment to mean Trump was taking credit for helping in the rescue and cleanup effort at Ground Zero (inspiring #LostTrumpHistory).
On the campaign trail in 2016 Trump said he helped with clearing the rubble.
"Everyone who helped clear the rubble — and I was there, and I watched, and I helped a little bit — but I want to tell you: Those people were amazing," Trump said at a rally in Buffalo. "Clearing the rubble. Trying to find additional lives. You didn't know what was going to come down on all of us — and they handled it."
The Washington Post and the Associated Press sought information from the Trump campaign in 2016 about how he helped, and they didn’t receive responses. We also tried to verify his claim and could not.
