Robert Mueller released his final report to current AG William Barr who then, in a surprisingly short period of time, released a four-page summary of the findings.
The two points of the investigation were: did Trump or his campaign collude with the Russian government to effect the 2016 election; did Trump commit obstruction attempting to influence the Russian investigation. Mueller seemingly punted on the obstruction charge, but did reach a conclusion about the Russian collusion: Trump and his campaign did not actively conspire with the Russian government in order to win the election.
