Financial dealing are within the scope as is anything he finds while Investigating.
Trump can point out conflicts..but if he fires mueller it will blow up in his face at this point. As I believe Jim N. said early on..he needed to do the firing right away.
Trump clearly doesnt want his taxes or business dealings Investigated. Doesnt mean he did anything wrong in them..might just fear leaks..and rightly so.
The scope is not what you claim, "anything he finds while Investigating." Make the argument within the language of the authorization given to Mueller, not some made up universal grant. How are 2008 or 2013 financial dealings of campaign advisors, directly related to "any links and/or coordination between the Russian government and individuals associated with the campaign of President Donald Trump."
You are parsing the grant as "directly related to individuals associated with the campaign of President Donald Trump." That amounts to open season on those persons, without having to associate the transaction with the campaign.
I find the scope to be links between Russia and the campaign. A financial deal that is not part of a link between Russia and the campaign is not part of the authorization given to Mueller. The only reason "individuals associated with the campaign" appears in the authorization is that a campaign cannot commit a crime, only people can.
I take you you disagree, and find that DOJ Order 3915-2017 authorizes open season on all individuals associated with the campaign.
