I already provided sources in another comment. This was part of the "he's a madman" narrative before the Russia collusion hoax.

The news obsessing over Trump bad every night is a scary reasoning for not wanting him in office. It means the propaganda and efforts to disenfranchise people are successful. Trump didn't lie any more than any other President and often his lies are trivial things. Not like Bush lying about Iraq having WMDs or Biden lying about not getting 10% for the big guy and being involved in Hunter's foreign business operations. The media is deciding how many lies they're going to attempt to find and put on the news. I'm sure Trump has said some serious lies too but the media making a mockery of themselves only serves to cover those up by creating noise.

This plays into your first question. Trump said he would be a dictator just on the first day to close the border and promote domestic oil. The media, and Biden, is now parroting that he said he would be a dictator "on day one." That is what he said, but he said for one day, not "forever after starting day one." It's a joke and frankly bait for the media and democrats. They are fake news and dishonest. They even went to court with the defense that they aren't real news agencies just entertainment to avoid following laws actual journalists are supposed to follow.

You can see another example of this in the story I just HAD to sign up to Lemmy in order to respond to. That Trump said "even if you freeze to death it will be worth it to go vote for him in Iowa." The news, and Lemmy, are clutching their pearls. Trump cares so little about you he doesn't care if you freeze to death! It's a joke! And it's made all the more funny by people trying to mischaracterize it as a serious statement. Trump is going to do this, over and over, because Americans find it absolutely hilarious. Just look at this post and the comments:

These people who refuse to let Trump tell a joke will get him reelected because it's funny watching them try to act like Trump is being serious.

You're not American so you don't really get it. COULD Trump be a dictator? Not if our government works the way it is supposed to. The very premise of a President becoming a dictator is funny to Americans and made all the more entertaining because Congress has tried to make the President a dictator and now they're walking back their own actions in the face of Trump. The AUMF and them discussing removing it is a great example. Here is one of the central core responsibilities of Congress, authorizing war, and they legislated it away and gave the President that power but NOW they want to take it away because someone that isn't part of the club might have those powers so they're concerned. There is a much larger context at play as to why this is so funny and why people focusing on these jokes will only further promote Trump. I'm sorry but you definitely will be hearing about it on the news every single night because it's extremely entertaining and that's why the "news" who characterizes itself as entertainment and not news will keep promoting it.

Trump and his supporters never organized a violent attack on the Capitol so I'm not sure what point you're making there. Believe me, if he and his supporters had ORGANIZED AN ATTACK on the Capitol it wouldn't have looked anything like Jan 6. The crowd at the capitol was made up of federal agents, MAGA idiots, BLM, antifa, and so on. The only person killed there was standing right next to a BLM person who is the one who kept shouting at her to climb through the window. You could just as easily say Biden and his supporters organized nation wide rioting, looting, and murder. Many, many more people died as a result of BLM associated rioting than did at the Capitol. There was billions of dollars in damage done all around the country. Except, that would be disingenous, Biden and his supporters didn't organize that. You can't mischaracterize tens of millions of people by the actions of a few hundred. Neither the BLM rioting or the Capitol incident involved more than a few hundred people and neither was approved by, organized by, or involved with Trump or Biden.
