Sigh, he explained what could be considered obstruction (which Comey said he was leaving up to Mueller to decide), and what his thought process was to the senate intelligence committee and to the American public. Period, from Comey's own mouth. Watch the testimony before you just bleat back what Trump told you think.
And pity me all you want, try to teach a legal class based on your google searches, call Comey a leaker and a snake, but it doesn't matter. Trump is 6 months into his presidency and is a lot deeper into the Russia investigation than anyone thought he would be 3 months ago, or even 10 days ago, and at best, he will be suffering massive political consequences as a result of it, with no end in sight, and his white house is going to be burdened (legally, financially, and psychologically) on a daily basis by Mueller's investigation. Nobody knows what Mueller will find in his investigation, but based on the dishonesty by Flynn, Kushner, and Trump Jr. about all things Russia, odds are that this isn't the last surprise.
But yeah "fake news," "no obstruction, no collusion, he's a leaker," "lock her up", "build the wall and Mexico will pay for it," and "grab em by the pussy," etc., etc.,
