Actually, it appears I'm of the opinion that obstruction of justice is a legitimate cause for impeachment. Moreover, there is precedent. When Congress prepared to impeach Nixon, they found 3 legal grounds for impeachment, "
obstruction of justice,
abuse of power, and
contempt of Congress".

The truth isn't biased comrade, it's just the truth. Just because you don't like the truth, it doesn't make the truth biased. Several proofs have been offered. Just because you refuse to see or acknowledge them it doesn't follow the proofs have not been offered comrade. Just where is it you see any ambiguity comrade? Unfortunately for you and those of your ilk there is none. That's why your man, Comrade Trump, is the subject of an FBI investigation. That's why one of his closest advisers who just a few months ago declared that taking the 5th was proof of guilt has now taken the 5th.
Every US intelligence and several foreign intelligence agencies have concluded Trump was Russia's candidate of choice. That's why Russia spent so much time and effort to get Trump elected. That's why Russians celebrated Trump's election. Did you miss all of that or are you still just denying all evidence? Before you go calling others biased comrade you had best take a long and very serious look at yourself.
EVIDENTIARY PROOF: apparently you don't understand the words you use comrade.
