There is no doubt that we MUST focus on Trump's admin at this time. 
Mueller has to be allowed to complete this with no more outside interference.

However, once Mueller is done, I am fine with letting him or somebody else investigate Uranium one deal in greater detail. 
we have traitors in our current admin and they have to be stopped, caught, and punished.
BUT, if we have more in our previous admin, then they have to go down as well.
