People on Twitter are mocking President Donald Trump's groundless claim Monday that he joined first responders at Ground Zero on 9/11.

"I was down there also, but I'm not considering myself a first responder," Trump told 9/11 first responders and others who had lost friends and colleagues in the attacks. "But I was down there. I spent a lot of time down there with you."

Trump's claim drew criticism and incredulity. There is no evidence to support the assertion that he was among first responders at the scene of the attack.

We do know that on 9/11 he spoke to a WWOR-TV reporter by phone, and falsely claimed that, with the World Trade Center gone, a buidling he owned nearby had just become the tallest in the area.

Many people on Twitter responded with humor, posting images on Twitter under the hashtag #LostTrumpHistory  which insert Trump into events from history: 

Others pointed to Trump's long history of dubious claims about 9/11, including the debunked claim that Muslims in New Jersey celebrated when the Twin Towers collapsed. 

It's not the first time in recent weeks that the president's take on history has been mocked.

On July 4, a speech he gave in Washington, D.C., claimed that the 18th century American army in the Revolutionary War "seized airports" from the British.

He later blamed the mistake on his teleprompter.
