Donald Trump's treatment of the family of a fallen U.S. Army captain who has spoken out against him repeatedly since appearing at last week's Democratic National Convention is "not a fatal blow," former New York City Mayor Rudy Giuliani said Tuesday. At the same time, the Trump supporter was blunt about how the Republican nominee could have better navigated the situation and offered his help to counter such episodes in the future.

"Look, I think it could have been handled better. I think he knows that," Giuliani told "Fox & Friends," while comparing Trump's comments to what he characterized as Hillary Clinton "lying directly to Gold Star mothers" as secretary of state about the 2012 Benghazi attacks.


Giuliani clarified that he was referring to Pat Smith, mother of U.S. information management officer Sean Smith, who was killed in Benghazi. Smith spoke at the Republican National Convention, and the Khans spoke at the Democratic gathering a week later.

"Yeah, my advice to Donald would be very simple. I'll tell you the advice I'd give him," Giuliani said. "You have one person to attack: Hillary Clinton. And Barack Obama because it's the Obama administration."

He continued, "Let all of us — myself, [Newt] Gingrich, [Chris] Christie, his whole army, let us attack everybody else. That's always been my rule in politics, which is, 'You're running against one person, don't run against the world.'"
