"You can ask General Kelly".
CNN asked the White House to talk to Kelly about this issue, but they declined to make him available.
The president's remarks came a day after he falsely said that Mr Obama and other presidents did not call the families of soldiers who were killed in action. "The toughest calls I have to make are the calls where this happens, soldiers are killed", Trump said, answering a question about four U.S. Special Ops troops killed in Niger two weeks ago.
"I write letters and I also call", Trump said of himself. I don't know. That's what I was told.
Several former aides of Obama called Trump a "liar" as soon as he made the comment..
A White House official on Tuesday told NBC News that President Obama did not call General Kelly.
Kelly's son Robert died in combat in 2010 in Afghanistan when he stepped on a bomb.
McCain, chairman of the Senate Armed Services Committee, told The Hill he has been "waiting for weeks and weeks" for information related to the ambush that took the lives of four Green Berets in the African country October 4. "But when we got on Marine One to fly back to the White House, the president was looking out the window, and then he looked at me and he said, 'That mama sure was mad at me.' And then he looked out the window and he said, 'And I don't blame her a bit.' And a tear rolled down his cheek, but he didn't wipe it away, and then we flew back to the White House".
The ostensible point of Donald Trump's press event at the White House yesterday was for the president to make the case that his presidency is succeeding, all evidence to the contrary notwithstanding. I don't know what (George W) Bush did.
Trump said on Monday he'd written letters to the families of the slain American soldiers, and planned to phone them in the near future.
A spokesman for Obama declined to comment. "I have called, I believe everybody, but I will use the word virtually everybody". "That's what I was told".
"Trump's jaw-dropping, disrespectful lie is not based anywhere in reality and is another symptom of a deep-seated obsession with tearing down President Obama".
Pressed later in the news conference, Trump admitted he didn't know what Obama's practice was in regard to the families of fallen soldiers. Also: "Obama never attacked a Gold Star family", Rhodes wrote on Twitter. I am not speaking for other people. "They've been sent, or they're going out tonight", the president told reporters.
Trump said Tuesday that he "will be calling, have called, and will be calling the parents and loved ones, wives of the soldiers that recently were killed" but that he wanted to wait for the right time.
