Michael Flynn's resignation was the first falling domino that led to Attorney General Jeff Sessions' recusal from the Russia investigation, which led to everything else that happened since.
Flynn resigned on February 13, 2017 over allegations that he spoke to Russian Ambassador Sergey Kislyak and didn't fully brief Vice President Pence about it.
On March 2, 2017, a little more than two weeks later, Jeff Sessions recused himself because he, too, spoke to Ambassador Kislyak and didn't mention it to the Senate Judiciary Committee during his confirmation hearing.
I'm saying that Kislyak was weaponized by the Democrats to take down any Trump appointee who spoke to him during the campaign or before his inauguration. Sessions would not have been challenged over his recollection of speaking to him had Flynn not been manipulated by the MSM to resign over "misleading" the Vice President.

What a fool Jeff Sessions was, and he will have to live with that decision the rest of his life. He turned tail and ran, without even letting his boss know his intentions. President Trump should have accepted his resignation back in 2017 when it was offered. My mother always said everything comes out in the wash, and although you might not think so at the time, things usually do work out for the best in the end. The fact that this stuff is coming out now in the months before the election, are a plus for President Trump in the long run. He's being vindicated for everything he's claimed all along.
