Well I have heard/read both sides of the argument. Some say it was correct for Obama to keep silent on Russia involvement in the 2016 election whereas others disagree.
Obama White House Knew of Russian Election Hacking, but Delayed Telling
How say you?
I think the article points out the main problem:
We had a candidate (Trump) that was already calling into question the validity of the election process. If Obama had more publicly announced the Russian interference, it would have been spun as a political move to discredit that candidate. Even worse, it would further degrade trust in the election, destabilizing our democracy, which was probably just as much a motive for the Russians as getting Trump elected was. And, Trump, unwittingly, played right into that narrative.
Our intelligence agencies were obviously working on the issue, and officials who needed to be informed were informed. The public was informed Oct 6th. Obama also placed sanctions on Russia for the election interference, which the Trump administration sought to immediately lift (I don't think they actually did it though).
So, the Obama administration did seem to respond appropriately to the threat, while trying to walk a fine balance to maintain a peaceful democratic process. The main beef regarding his handling seems to be that he didn't do enough to inform the public. I agree that more could have been done. I also agree that this could have backfired. I imagine that we would have had just as many people, if not more, believing that the Russian interference was a political hoax designed to hurt Trump.
Which, unironically, is the stance that many Trump supporters had been holding until the evidence became undeniable, including Trump himself.
