'Just look at her pathetic email and server statements, or her phony landing in Bosnia where she said she was under attack but the attack turned out to be young girls handing her flowers, a total self-serving lie,' Trump said.
The comment was a reminder of a flap from Clinton's 2008 campaign, where she boasted about landing in Bosnia under sniper fire, when contemporaneous video showed a friendly landing.
'Brian Williams’ career was destroyed for saying far less,' Trump said,delivering another blow comparing him to the former NBC anchor who had to give up his perch after he was found making a series of exaggerations.
Hillary Clinton's camp had no immediate response to the speech.
Marcy Stech of the group Emily's List, which backs Clinton, released a statement in reaction to Trump's shameful, dishonest speech about Hillary Clinton.'
'Believe me, Donald Trump is a world-class fraud and his lies are a disservice to the nation,' she said.
Trump laid the Benghazi attack squarely in Clinton's lap. Trump said, 'Her decisions spread death, destruction and terrorism everywhere she touched.'
He blamed Clinton for the death of the late U.S. ambassador to Libya, who Clinton considered a friend. He died after terrorists stormed a U.S. embassy compound and CIA annex.
'Among the victims is our late Ambassador, Chris Stevens. He was left helpless to die as Hillary Clinton soundly slept in her bed -- that's right, when the phone rang at 3:00 in the morning, she was sleeping.'
