The country needs this investigation

For two years, we've been hearing about Russia and the 2016 election.  Just two weeks ago, Robert Mueller concluded that there was no "collusion" between Russia and the Trump campaign.

Nevertheless, many of us are still curious about why the investigation happened in the first place.

Who initially approved this and why?

Thankfully, A.G. William Barr is curious, too.  He wants more information, as the AP reported:

Attorney General William Barr has appointed a U.S. attorney to examine the origins of the Russia investigation and determine if intelligence collection involving the Trump campaign was "lawful and appropriate," according to a person familiar with the issue.

Barr appointed John Durham, the U.S. attorney in Connecticut, to conduct the inquiry, the person said. The person could not discuss the matter publicly and spoke Monday to The Associated Press on condition of anonymity.

With the appointment, Barr is addressing a rallying cry of President Donald Trump and his supporters, who have accused the Justice Department and FBI of unlawfully spying on his campaign.

Spying, for sure.  However, there is more to it than that:

1. Who gave FBI director Comey the authority to announce that there would be no prosecution of Hillary Clinton's emails?  Why didn't A.G. Loretta Lynch make that call in public?

2. Who approved the FISA warrant apparently based on a flawed document?  Who knew?

3. Why were FBI agents texting each other about the Trump campaign during work hours?

There are more questions, of course.

The country needs to know the good or bad of what happened.  Maybe it was all legal and by the rules.  Maybe it was not.  One way or another, I am curious and would like some answers.
