Former Attorney General Eric Holder called out President Donald Trump’s false remark about former POTUS Barack Obama on Monday, where he claimed that his predecessor did not care enough personally call the families of fallen U.S. soldiers.

Holder urged Trump to “Stop… lying,” posting a photo that showed him standing alongside Obama in the Dover air force base, Delaware, where both of them comforted the families of the fallen soldiers of the Military and the DEA.

Holder’s tweet was sparked from a comment that Trump made during an impromptu press conference that he held in the White House Rose Garden on Monday afternoon.

During the conference, he was asked about his silence following the killing of four Army Green Beret soldiers in Niger on Oct. 4. At this, the president replied saying that he had personally taken the time to write a letter to each one of their families and that he would call them up at “some point.” He went on to remark that while he finds ample time in his busy schedule to attend to something like this, Obama never made it a priority.

"Now it gets to a point where you know, you make four or five of them in one day, it’s a very, very tough day," Trump said, The Star reported. "For me, that’s by far the toughest. So the traditional way — if you look at President Obama and other presidents — most of ’em didn’t make calls, a lot of ’em didn’t make calls. I like to call when it’s appropriate when I think I’m able to do it. They have made the ultimate sacrifice. So generally I would say that I like to call."

However, as soon as NBC reporter Peter Alexander challenged Trump to present proof of the fact that his predecessor did not care about the families of U.S. soldiers, the president started to backtrack on his allegation.

“I don’t know if he did,” Trump said. “I was told that he didn’t often, and a lot of presidents don’t. President Obama, I think, probably did sometimes, and maybe sometimes he didn’t, I don’t know, that’s what I was told. All I can do is ask my generals.”

This is not the only time that Trump had refused to take responsibility for the inaccuracies in his knowledge about a subject. After he falsely claimed back in February, during a press conference that he had won with the biggest Electoral College margin of victory since former President Ronald Reagan, he was challenged to prove the fact by a reporter. “I was given that information,” Trump said at the time.

Many Twitter users reacted to Holder's evidence that defended Obama's honor and presidential record:

During Monday’s press briefing, White House Press Secretary Sarah Huckabee Sanders defended Trump’s comment by saying that the president was “stating a fact” when he said that many of the former presidents did not habitually call the families of fallen soldiers. She further directed a statement to all the former Obama aides: “Individuals claiming former presidents, like their bosses, called each family of the fallen, are mistaken.”

However, former Obama aide Tommy Vietor told the Star: “President Obama spent time with families of the fallen throughout his presidency through letters, calls, visits to Section 60 (for soldiers killed in the War on Terror) at Arlington and regular meetings with Gold Star families.”
