The many ways that Mitch McConnell obstructed truth for political gain:
What did he say about how his tax cut would affect the deficit:
To paraphrase he said, I am confident that the tax cuts are not just revenue neutral but will be a revenue producer.
And now the deficit soars to a six year high.
What did he say about the Russian election tampering:
The Washington Post reported:
In early September, Johnson, Comey, and Monaco arrived on Capitol Hill in a caravan of black SUVs for a meeting with 12 key members of Congress, including the leadership of both parties. The meeting devolved into a partisan squabble.
The Dems were, Hey, we have to tell the public, recalled one participant. But Republicans resisted, arguing that to warn the public that the election was under attack would further Russias aim of sapping confidence in the system.
Senate Majority Leader Mitch McConnell (R-Ky.) went further, officials said, voicing skepticism that the underlying intelligence truly supported the White Houses claims.
As Brian Beutler put it, McConnell ran interference for Trump during the campaign to stop Obama from warning the country about things Trump was lying publicly about.

What did he say to obstruct Merrick Garland:
"The American people should have a voice in the selection of their next Supreme Court Justice. Therefore, this vacancy should not be filled until we have a new president," McConnell said.
McConnell went on to consistently oppose holding hearings on President Barack Obamas nominee, Judge Merrick Garland.

What did he say about Kavanaugh:
Youve watched the fight. Youve watched the tactics. But heres what I want to tell you: In the very near future Judge Kavanaugh will be on the United States Supreme Court, McConnell said.
Keep the faith. Dont get rattled by all of this. Were going to plow right through it and do our job, he added in reference to the allegation that Kavanaugh trapped Ford in a room, pinned her to a bed, groped her, tried to strip her naked and covered her mouth when she tried to scream.
