<But there's no evidence to back up what you allege.>
What have I alleged?  That Russia interfered with the 2016 election in an effort to help Trump is beyond dispute.  That Trump and his team have lied repeatedly about their contacts with Russia is also beyond dispute.  Exactly why they are lying -- exactly what they are covering up -- is not yet fully known, but is the subject of several ongoing investigations.  Likewise, the extent to which Russia succeeded in affecting the outcome of the election is also not yet known, but also the subject of ongoing investigations.  
To describe those investigations as "essentially personality issues" is a lie of truly Trumpian proportions.  Nothing and no-one is "hurting the nation" more than the presidency of this corrupt, incompetent, unstable president is hurting it.
