This has NOTHING to do with who won or lost the election; it is about perjury. While under oath, Sessions lied to the U.S. Senate. Even if it were proved tomorrow that Russia did not interfere in the election in any way, Sessions would still be guilty of lying.

It's the Trump administration, not the press, that can't get their facts straight. Describing the meeting between Sessions and Russian ambassador Sergey Kislyak, a Justice Department official said, “There’s just not strong recollection of what was said.” Then a White House official told CNBC that there was “superficial” discussion of the election. Finally, Sessions said that he “never met with any Russian officials to discuss issues of the campaign.”

So there are 3 Trump administration stories:
1) they met, but no one remembers what they talked about, or
2) they met, and they do remember talking about the campaign but only briefly.
3) they never met
It's like a child's choose-your-own-adventure book.
