Rudy Giuliani, President Donald Trump's personal lawyer, gave a warning to Hillary Clinton after she said Trump would have been indicted for obstruction of justice if he was not in office.

Talking on "Fox & Friends" Wednesday, Giuliani said Clinton actually committed obstruction of justice during the investigation into her emails and private email server and the old rule of never indicting a Clinton will soon change.

"I have a hard time reacting to that I mean, there's a woman who really obstructed justice," Giuliani said. "The president didn’t delete 33,000 emails. He didn’t have somebody smash up telephones. And he didn’t have someone wipe out a server and BleachBit it among the few things that she did. The president was innocent of the underlying crime."

"Collusion delusion. No collusion. If you are innocent on the underlying crime, then everything they are talking about is an effort for him to defend himself," he continued. "If I tell somebody that I’m innocent, please, testify on my behalf and say what happened, am I obstructing justifiable or am I defending myself and serving justice. But these demented prosecutors never heard that in American law or English law or Roman law or any law, they turned it in we assume is he guilty. If he says to somebody don’t cooperate or cooperate, he is saying it because he wants the truth to come out."

"There used to be a DOJ standing policy you can’t indict a Clinton, no matter how much they obstruct justice, no much matter how much evidence they destroy and how often they lie, and no matter they committed perjury. You can’t indict a Clinton, it’s against the Democrat Justice Department rules," he said.
