It would seem, given the Mueller probe indictments, that POTUS might jawbone Russia & its patron saint for 2016 election meddling, same as he jawbones other countries, friend & foe alike. It would seem.
Because he never does - and in fact says opposite every opportunity he gets - in stark contrast to how he treats every other country he talks about. This has nothing to do w/ delegitimizing an election. It has to do w/ meddling, which happened.
