Sorry dude, but the Russians hacked into 38 states electoral systems. The weren't able to do much - supposedly - but they still hacked them 
As far as Obama: It took time before the scope and breadth of the cyberattacks became known; in fact, that info wasn't fully known until well after Trump was fake-elected.   Ironically, Obama was concerned with adversely affecting the election if the full extent ( at the time) of cyber hacking became public. 

As far as this investigation taken no a load no time: A year is not a long time; they typically take years. Where was your whining when Clinton was investigated - and cleared - 8 TIMES in relation to Benghazi?  So STFU about this investigation; it's barely begun, and we know there's a lot out there waiting to be discovered. So does Trump, which is why he's so paranoid. 

And now Pence gas lawyered up.
