I agree he has lied and to the FBI of all agencies to lie to. He tried to undermine the USA not good!
And I respect your opinion that it could be a coincidence and I will acknowledge that is possible, however:
According to the indictment his emails show approx mid March he started emailing trying to get a meeting...
April 26, 2016 he was informed by foreign agency that they had "dirt" on HRC.
May 21, 2016 he emailed Manafort about meeting to get said "dirt".
June 9, 2016 Kushner, DTJ and Manafort meet with foreign agency to get "dirt" by DTJ own admission.
I don't think it was a coincidence looking at the timing of the emails and the eventual meeting DTJ admitted to, but reality is that Mueller has access to Pop's email and who all was on the email chains.
Meeting 3ish weeks after emailing Manafort about setting up a meeting is pretty suspicious to me and apparently the FBI.
ETA: 3ish weeks from POP's email to Manafort and the actual meeting Manafort and DTJ had with foreign agency to get "dirt". If a coincidence, and I will concede there are some strange coincidences, it's one for the books that an email that the FBI have in their possession to Manafort about a meeting ended up actually happening.
Okay let's say the dirt that was offered to Papadopouls is the same dirt that was offered to Manafort by someone else. What is the significance?
