Obama didn't call John Kelly when his Marine son died in action, White House official says

Trump has said "most" past presidents didn't call families of the fallen.

— -- Adding to the continued drama over whether past presidents have called the families of fallen soldiers, a senior White House official told ABC News today that then-President Obama did not call John Kelly, now the White House chief of staff, after the death of his son in 2010.

But the breakfast, scheduled to be hosted by the Obamas, was six months after the death of Kelly's son. It's unclear whether President Obama contacted Kelly about his son in any way prior to this.

President Obama's office did not respond today to a request for comment on whether he contacted Kelly in another way.

"If you look at President Obama and other presidents, most of them didn't make calls, a lot of them didn't make calls. I like to call when it's appropriate, when I think I'm able to do it," Trump said at a news conference in the White House Rose Garden Monday.

When asked about his comment that Obama didn't call the families of the fallen again later in the news conference, Trump said, "I don't know if he did. I was told that he didn't often. And a lot of presidents don't; they write letters. I do.”

"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 -- all I can do is ask my generals,” he added.

“Other presidents did not call. They’d write letters. And some presidents didn't do anything. But I like the combination of -- I like, when I can, the combination of a call and also a letter.”

A former Obama official said Trump's Monday Rose Garden statement – and not specifically addressing the claim about Kelly -- was "unequivocally wrong."

"President Obama engaged families of the fallen and wounded warriors throughout his presidency through calls, letters, visits to Section 60 at Arlington, visits to Walter Reed, visits to Dover, and regular meetings with Gold Star Families at the White House and across the country," the former Obama official said in a statement to ABC News.

Freddy Ford, a spokesman for former President George W. Bush, also issued a statement noting his outreach to the families of fallen soldiers.

"President Bush wrote all the families of the fallen, and called and/or met privately with hundreds if not thousands," Ford said in the statement, issued Monday.
