Donald Trump on Wednesday compared Hillary Clinton’s account of coming under sniper fire in Bosnia to the embellishments that infamously got NBC’s Brian Williams suspended from his job.

During a wide-ranging speech attacking Clinton at Trump SoHo in New York City, Trump brought up an incident where Clinton had said she “landed under sniper fire” at an air base in Bosnia during a visit as first lady.

“Most people know she’s a world class liar,” Trump said. “Just look at her pathetic email server statements or her phony landing—or her phony landing in Bosnia where she said she was under attack, and the attack turned out to be young girls handing her flowers.”

Clinton’s account was disputed by several journalists and colleagues, and during the 2008 election the former first lady and said she “may have misspoke.”

Trump compared the story to those told by Williams, who was suspended from his job as an anchor for NBC News for six months after it was revealed he embellished an account about being in a helicopter that came under fire in Iraq, among others.

“Look, this was one of the beauts, a total and self-serving lie,” Trump said of Clinton’s Bosnia recollection. “Brian Williams’ career was destroyed for saying less, just remember that.”
