I know you're not responding in good faith, but I want to respond with actual quotes from the Mueller report, since this is on a public forum.
> "While this report does not conclude that the President committed a crime, it also does not exonerate him."
> "[I]f we had confidence after a thorough investigation of the facts that the President clearly did not commit obstruction of justice, we would so state. Based on the facts and the applicable legal standards, we are unable to reach that judgment."
> “Our investigation found multiple acts by the President that were capable of exerting undue influence over law enforcement investigations, including the Russian-interference and obstruction investigations,” Mueller wrote. “The incidents were often carried out through one-on-one meetings in which the President sought to use his official power outside of usual channels. These actions ranged from efforts to remove the Special Counsel and to reverse the effect of the Attorney General’s recusal; to the attempted use of official power to limit the scope of the investigation; to direct and indirect contacts with witnesses with the potential to influence their testimony.”
> "the President engaged in a second phase of conduct, involving public attacks on the investigation, non-public efforts to control it, and efforts in both public and private to encourage witnesses not to cooperate with the investigation."

In case it's not obvious, the point of obstructing justice is to prevent facts from coming out.
