Because there is little defense for so many of Donald Trump's actions, a common response / defense for Trump's supporters is to deflect by saying "don't look at Donald Trump's actions," look at some other person's wrongdoings instead. However, other people's wrongs do not justify Trump's wrongs and other people's wrongs are irrelevant as to whether Trump was right or not. Each person should be judged on their own set of facts. Two wrongs do not make a right.
If we keep on justifying bad behavior by our politicians by pointing to bad behavior by other politicians, I have no idea how you expect to clean up Washington. If you want to clean up Washington, you need to advocate holding bad Republicans and bad Democrats accountable.
As to "what did Trump do that was illegal", read the indictments. If it can be shown that he knew he was lying and that he knew he lost the election, then he knew his actions were illegal and he is guilty.
Addressing your "look over here" deflection, unlike Donald Trump's actions relating to the January 6 riots, Kamala Harris' actions were not the primpary cause of the BLM riots. The fact that Donald Trump's actions and rhetoric were the primary cause of the January 6 riots IMO puts his participation in the Capitol riots at an entirely different level than Kamala's participation in the BLM riots. That being said, if Kamala did something criminal in relation to the BLM (which I am unaware of), then I agree she should be held accountable, regardless of how bad Trump's actions may have been.
Trump’s actions were not the primary cause of Jan6. In fact he said to protest peacefully and make your voices heard.
Here’s the primary cause: The country was a ticking time bomb primed by five years of baseless attacks.
Four false FISA applications. A fake Russian dossier.
Top FBI officials conspiring to stop Trump.
Framing and bankrupting a four star general to get at Trump.
Imprisoning his staff for things everyone in DC does.
Intel bigwigs lying about Hunter’s laptop being a Russian plant.
The FBI, DOJ, CIA and more intimidating news casts and massive tech/social media firms into suppressing negative news about Biden.
Hildebeast brazenly laughing at how she was given a free pass for major intel violations.
Bill Clinton brazenly laughing off a secret meeting with AG Reno.
The DNC refusing to cooperate with the FBI.
A top DNC staffer blatantly murdered in the middle of the government campus of DC and no investigation into his murder.
Massive raids with media tipped off to get maximum publicity while arresting older cooperating witnesses.
Innocent people like Carter Page snd George Popodopulous bring framed and bankrupted on defending themselves.
Anyone that supported Trump being called racist, sexist, homophobic, xenophobic, retarded, knuckle dragging Neanderthals,
Being harassed at work, banned from campuses, ridiculed endlessly by media and entertainment types.
