Rudy Giuliani lashes out at Fox's Andrew Napolitano -- then gets schooled on obstruction by an ex-prosecutor

Fox News legal analyst Andrew Napolitano often delivers the bad news to the network's conservative viewers about President Donald Trump's potential legal exposure -- and Rudy Giuliani doesn't like what he's hearing.

The president's personal attorney ripped Napolitano, a former New Jersey Superior Court judge from 1987 to 1995, for declaring Attorney General William Barr's defense of Trump's possible obstruction "absurd."

But Mimi Rocah, a former assistant U.S. attorney for the Southern District of New York from 2001 to 2017, said Giuliani was dead wrong.

Rocah, now an MSNBC legal analyst and criminal justice fellow at Pace University Law School, said the evidence uncovered in special counsel Robert Mueller's investigation did not support Giuliani's argument.
