Not going to happen. The situations with Clinton and Obama were merely political stunts from the Republican Party to rile up the ignorant to vote Republican. Mueller and his team have more important things to do than investigating on some fake reason just so the Republicans can gain political points. There is evidence of Russian meddling and it's up to our intelligence community to get to the bottom of this whether Trump had no connections to this or not. The Rusian investigation isn't about Trump colluding with Russia or not, it's about his CAMPAIGN having any collusion with Russia. 

If Trump has committed any sort of obstruction of justice, then he needs to face justice and have Mike Pence take over.
