White House visitor records from former President Barack Obama’s term show that he hosted current White House chief of staff John Kelly at a breakfast for Gold Star families after his son died in Afghanistan.

In a Fox News Radio interview, President Donald Trump defended his claim that his predecessors fell short in honoring those killed in action by saying: “You could ask Gen. Kelly, did he get a call from Obama?”

Former aides to Obama say it’s difficult this many years later to determine whether Obama called Kelly and when.

The breakfast for relatives of U.S. troops killed in action occurred in May 2011, six months after Kelly’s son died. An individual familiar with the breakfast for families of says that Kelly and his wife sat at former first lady Michelle Obama’s table. The individual demanded anonymity because the event was private.
