Minor legal point here - even IF Mr. Trump "
knew about the Russian help, welcomed it and expected to benefit from it" that is NOT sufficient to establish a "conspiracy". In order to establish a "conspiracy" one would also have to establish that Mr. Trump was
actively involved in the planning and/or implementation of "the Russian help".
There is absolutely no evidence that Mr. Trump was
actively involved in the planning and/or implementation of "the Russian help" and the fact that the Russians both knew what they were doing and were smart enough NOT to allow anyone with a personality profile similar to Mr. Trump's personality profile to even come close to being
actively involved in the planning and/or implementation of "the Russian help" mitigates strongly against Mr. Trump BEING A PARTY (as opposed to being a beneficiary) of whatever conspiracy was behind "the Russian help".
I guess you could liken the difference to the difference between
"someone who _arranges_ with people who are going to rob a bank to toss money money out the window of their getaway car in order to increase their chances of not being caught getting to the bank when the robbers are robbing it then standing around holding a bushel basket so that they can catch more or the tossed money"
and
"someone who _learns_ that a bank is going to be robbed and that the robbers are going to toss money out of the window of their getaway car in order to increase their chances of not being caught getting to the bank when the robbers are robbing it then standing around holding a bushel basket so that they can catch more or the tossed money"
with one set of activities being a conspiracy and the other not.
