Alan Dershowitz argued Friday that federal prosecutors seeking a “substantial term of imprisonment” for former Trump lawyer Michael Cohen is bad news for special counsel Robert Mueller.

“There are two possibilities,” the lawyer told Fox News’ “The Five.” “One, that Cohen hasn’t really provided them very much or hasn’t been completely cooperative. Or two, by recommending a very, very harsh sentence, they are putting more pressure on Cohen, maybe to come up with even more information because the government has the power to get the sentence reduced afterward if they can tell a court that there was cooperation.”
