Push who?
Trump? Trump says he never said anything of the sort.
Comey? Comey has been clear about what he understood the statement to mean. He intended both to not obey, if that's the correct verb, and to attempt to avoid any repercussions by trying to get Trump to interact with him through the Attorney General, as Trump should have been doing.
From Comey's opening statement:

The reason why leaders speak of such things using euphemisms and minimising language is so that if they're brought to account they can attempt to plead the exact sort of "misunderstandings" that you're putting forth here.
We all know what Trump meant. Nobody in their right mind would call Comey into the office and say "Drop the Flynn investigation or you're fired". That would be insane. If one wanted that done, one would couch it in softer, vaguer language and rely on the fact that anyone who has risen to the position of Director of FBI can understand basic nuance. I mean, why would the President express his hopes to his FBI Director unless he expected Comey to do something about it? It's not like they have a close personal relationship.
Trump clearly doesn't understand that some people might view themselves as independent actors and not beholden to him personally or to a political party. Comey obviously saw this coming a mile away which is why he took notes on everything and discussed it with work colleagues at the time to boot. Trump is going to have a hell of a time discrediting a witness like Comey. If it comes to he said, she said between Trump and Comey, everyone knows that Trump lies like a rug.
As far as I can tell, Comey serves America. Trump serves Trump. I hope Trump drags his tapes out so that we can all hear what was said.
