Not all the legal experts. There is no on point scotus precedent that can be pointed to. This case will be distinguishable from past instances of presidential abuse. Also, Trump used weasel words worthy of any mafia "don" but absolutely clear to anyone who has been around the block or seen any bad movies.
Two scenarios
1. Guy walks into a bar and says to beautiful women I hope you will suck my dick in the back alley by that dumpster.
2. Boss calls secretary in and says he hopes she will suck his dick under the desk, and asks if she would like to keep her job.
Both are reprehensible, but situation #2 far more so. It's flat out extortion and abuse of authority, and is on all fours with Trump's actions towards Comey, as he testified under oath.
So the question is whether the President of the United states has the absolute privilege to ask the director of the FBI to suck his dick under the desk or he will be fired. If the answer is Yes, he skates.
His consciousness of guilt is that he insisted on being alone, both to increase the likelihood of success, to shield and protect others from being party to his nefarious proposition and to prevent there being witnesses to a crime.
