WATCH: CNN shows 'astonishing' video comparing Rudy Giuliani's 'tough on crime' stance in the 1990s to defending crime in 2018

On Monday, CNN's Erin Burnett played an epic video taking down President Donald Trump's lawyer Rudy Giuliani.

Giuliani served as the mayor of New York in the 90s. However, his most recent actions defending the president are contradicting how he acted in his role as mayor.

The video showed videos of Giuliani being tough on small crime and saying that "small crimes lead to big crimes."

"Back then he Giuliani swore that you stopped big crimes by stopping small crimes," CNN reporter Tom Foreman said.

"The change is startling, he used to be a zealous prosecutor," Foreman said. "This is astonishing, this is a very big change for a man who once said 'there no such thing as 'small crimes.'"
