The tactic that President Garrison suggest to Randy, DARVO (Deny, Attack, and Reverse Victim and Offender) is an actual behavioral tactic, where a person accused of wrongdoing attempts to shift blame away from themselves and instead places it onto the accuser, while painting themselves as the real victim.

The row of tegridy jars at the end of the episode are labelled after the first six episodes of the season. The exception is the right most jar which was labelled "Tegridy Burger" instead of "Let Them Eat Goo".
President Garrison defending himself with DARVO as well as the Whites accusing Randy's trial to be a waste of taxpayers' money is in reference to the impeachment inquiry filed against President Donald Trump, who has been accused of asking for political favors from Ukraine, while he accuses the media of ignoring corrupt deals made with Ukraine and China by former Vice President and 2020 Democratic Presidential candidate, Joe Biden and his son, Hunter and believes that the impeachment inquiry is a scam.
President Garrison defending Randy and calling the Tweeks "Tampon Faced 69ing whistle blowers" for leaking the video is in reference to President Donald Trump demanding to know the identity of the whistle blower who has accused him of asking for political favors with Ukraine to help with the 2020 U.S. Presidential Election.
Randy and Towelie's podcast is a reference to the modern trend of podcasts in social media and streaming services.
The Whites point out the unsettling trend in recent years where people go nuts over anything bad that happens to a minority, but don't give a damn when something truly horrible happens to White People.
A real-life example would be an incident not too long after Trump's Election where four 18yr old Black kids kidnapped a mentally disabled White kid and Livestreamed themselves torturing him while saying "Fuck White People" and "Fuck Trump", yet the Media and Police Superintendent Eddie Johnson made excuses for them and tried to brush the whole thing off. 
Former New York City mayor and lawyer to President Donald Trump, Rudy Giuliani is depicted in this episode.
The crowd outside Randy's trial holding signs with and chanting "Lock Him Up" while only the Whites supporting him is a reference to Game 5 of the 2019 MLB World Series, where President Donald Trump was loudly booed by the majority of the audience who then then chanted "Lock Him Up" upon his arrival. A similar incident happened a few days later at a UFC match attended by Trump, though with significantly more cheers than boos. 
The song that plays at the house party is "Give Up The Funk (Tear The Roof Off The Sucker)" by Parliament.
