Legal ramifications
Partly at issue is whether Trump's comments to Comey represent obstruction of justice. Any such charge would rest heavily on the exact wording of Trump's comment, according to Columbia University law professor John Coffee.
Even if Trump's comments cross a legal line, it's unlikely such a charge could be brought against a sitting president, he said.
"It's generally believed that you cannot indict a sitting president, because that would paralyze the government," said Coffee. "And because impeachment is the constitutional procedure created to remove a president."
Coffee said an obstruction charge is also unlikely from the current Justice Department.
"Any U.S. attorney who brings an indictment can be overruled by the attorney general — even if the case is meritorious," he said.

it would be stupid for democrats in front of 2020 because it would help get out the vote for trump.
your link is irrelevant to the obstruction of justice question.
impeachment is completely different and not going to happen why republicans are in charge and it would be stupid for democrats in front of 2020 because it would help get out the vote for trump.
Impeachment has a large element of politics involved. The Republicans won't convict the President for anything he has done so far. Obstruction of Justice will be one of several articles of impeachment, i.e., high crimes and misdemeanors. Mueller will follow the money, just as DOJ attorney Bharara was doing before he was fired, to find out why Trump has been so obsequious toward the Russians. Rest assured there is a reason!* It is almost certainly a financial/real estate reason. Once this other shoe drops it will be curtains for dear Mr. Trump, our asshole President. Even a Republican Congress will impeach and convict once all the pieces of the puzzle are in place. As I said this is just the beginning of the Second Act. Those other puzzle pieces have just been hinted at in the First Act. They will be fully revealed late in Act Two. Possibly by late summer 2018. And won't that make for fine Television entertainment.your link is irrelevant to the obstruction of justice question.

*It is virtually certain that Trump has done something illegal under U.S. Law involving finance or a real estate transaction involving Russian money and that there is a connection between this transaction and the election hacking. Once that connection is made Trump is as good as gone. I wouldn't give you 2 cents for his chances of survival. Putin is setting him up. It is lovely to see, as there can not be anyone in the world more deserving than Trump.
