Trump is a big fan of Putin. Putin is a complete failure as a leader. He is a dictator. He has no political opposition in Russia to speak of. The vast majority of Republican and Democratic lawmakers clearly see Putin for what he is: former KGB thug, assassin, and all around bad guy, who (like Trump) only has his own personal and political interest in mind. Trump's fascination with and adoration of Putin could be his undoing.
The folks who are experts in this field have made a determination that Russian computers operatives, urged by Putin, sought to influence the US elections by means of hacking into Trump's opposition, HRC. They "meddled" with the election as best they could with the intent of hurting HRC.
Not sure what is so hard to comprehend.
And for the record, Trump began his morning with a Tweet attempting to insult former CA GOV Arnold Schwarzenegger and his less than stellar viewer ratings for the opening week of "Celebrity Apprentice." We are in for a long and sad ride with this idiot in the White House.
