Regarding no collusion but obstruction:

Regarding not being impeached for collusion:
The first impeachment had to do with trying to dig up dirt on Biden by threatening to withhold military aid and a WH visit from Zelensky if he didn't help. It was then claimed Trump tried to obstruct the investigation. This had nothing to do with Russian collusion.

The second impeachment had to do with Trump trying to stop Joe Biden from taking office after being legally elected to the Presidency. This also had nothing to do with Russian collusion.

As far as a mob that tried to forcibly remove Trump from office or tried to prevent him from carrying out his duties as POTUS, I can't find that. If you can from a reliable source, I will yield. But that's never really been reported by anyone that I know of, so it's kind of hard to find a source refuting it since it has not been reported anywhere.
A mob did try to prevent Joe Biden from becoming president.

Trump would always speak well of Putin in 2015 interviews. He would never admit to having met him or having spoken to him. He would also deny it. But in doing so, it was obvious he wanted the viewers to believe he had and would make things better with Russia if he were POTUS.
He later in one interview said he had met him many years before.
He then continued to not answer whether he had met or had not met him.
He then talked about being stablemates with him on 60 minutes and being on 60 minutes together, he got to know him well.
Then once the calendar turned over to 2016 and it was looking like he had a real chance to win the Republican nomination, he continued to praise him, but denied ever meeting him or having business dealings with him in Russia.
There were plenty of links between Trump's campaign and Putin and Russia.
I don't think there was ever clear evidence Trump, himself, colluded with Russia. But Trump was more than happy to get their help.

One of the great conservative pundits. Sadly, he passed away not long after writing this.
