Former Deputy Assistant AG John Yoo explains why Michael Cohen's testimony is so disastrous that it should trigger a mistrial:
"Jim and I were both at the Justice Department... we would never have authorized a prosecution like this that was so dependent on someone who has been convicted of federal crimes for lying."
"Did we cross the Rubicon? Did we go after a former president for the first time in the history of this republic, in 235 years, for this guy? For this kind of witness? For these kinds of charges?"
