in my mind, continuing to accept overtures and solicit help from Russia, knowing they were actively trying to interfere in the election, plus the various pro-Russia policies Trump has pushed is enough to establish something deeply wrong and deserving of removal of Trump from office. You can call it whatever you want-- collusion, tacit cooperation, willful blindness, negligence in failing to report or deter the actions of Russia. If the conduct was found to not be illegal because we do not have laws addressing that specific conduct, then we need to pass new laws to address it in the future. It is wrong, undemocratic, and unamerican, even it is not illegal today.
Moreover, I think the report caveats the findings of its investigation and in no way rules out the possibility of a broader conspiracy. We still do not know what Trump and Putin have discussed in their private meetings. Is there proof of an agreement there? What about all the lies to cover this up? What about obstructing an investigation designed to get to the bottom of the greatest attack on democracy in history? I am firmly in the impeachment camp, call it what it is: high crimes and misdemeanors. Let the traitorous republicans defend it.
