Transcript for Feds recommend 'substantial prison term' for Michael Cohen
We begin with the president tonight, and his longtime lawyer and personal fixer, Michael Cohen. Prosecutors urging a judge to sentence Cohen to substantial prison times, 42 months, saying he committed crimes motivated by personal greed. This case, in the southern district of New York. At the same time, another filing involving Cohen, this one from Robert Mueller's team. He was interviewed for 70 hours but that team, and saying the investigation has been credible and consistent with other evidence obtained. But they remain silent when it comes to any prison recommendation. Pierre Thomas leads us off. Reporter: Michael Cohen, leaving his home today, after imploring prosecutors not to put him behind bars. They did not buy it. Tonight, the U.S. Attorney in New York denouncing Cohen's "Extensive, deliberate, and serious criminal conduct," saying he "Sought to influence the election from the shadows," "Motivated by personal greed and ambition." The sentencing recommendation, a "Substantial prison term." Cohen, president trump's former personal attorney and fixer, pleaded guilty to crimes including tax evasion and making illegal campaign contributions. He admitted facilitating hush payments to porn star stormy Daniels and "Playboy" playmate Karen Mcdougal to cover up their alleged affairs with candidate Donald Trump, the man he once said he'd take a bullet for. I'm obviously very loyal and very dedicated to Mr. Trump. Reporter: But under fire, Cohen turned on his old boss, telling prosecutors trump ordered the hush money payments himself.

And lying about contacts with the trump administration, as recently as this year. Let's get to Dan Abrams. When it comes to Michael Cohen, there are two cases.

New York is talking about campaign finance and tax evasion. But Robert Mueller is saying he's been helpful, but we're not asking for any additional leniency in connection with that other case. We're okay if he serves his time for us as the other case, but we're not asking for anything below four to five years. So, a significant amount could be very likely. Yes, very likely. Dan, thank you.
