In an interview with NPR's Steve Inskeep that will air today on Morning Edition, Obama said...
"I think there is no doubt that when any foreign government tries to impact the integrity of our elections ... we need to take action. And we will — at a time and place of our own choosing. Some of it may be explicit and publicized; some of it may not be."
The President went onto say of Russia's President Vladimir Putin, who the intelligence community now believe directly ordered the hack...
“He is well aware of my feelings, because I spoke to him directly about it,”
Obama last met with the Russian President at the G-20 summit in September where he discussed the cyberattacks with him personally.
As for what actions the US might take Obama did not specify.
Earlier this month, he ordered a full intelligence probe of the matter, to be completed before he leaves office on Jan. 20 as did a bipartisan group of senators.
As for the damage the cyber-attacks caused the president said there was “no doubt" that it contributed to a narrative that helped the Trump campaign and hurt Clinton's
Obama also noted that the Trump campaign took full advantage of the cyberattacks and readily used them to their advantage.
In an interview with “The Daily Show” on Monday, Obama suggested that there were...
“very clear relationships between members of the president-elect’s campaign team and Russians, and a professed shared view on a bunch of issues.”
Trump has denied the allegations, calling them “ridiculous” and “just another excuse” as well as falsely claimed that the hacks never came up until after the election. This despite the fact that he himself brought them up on several occasions once even inviting Russia to hack Hillary clinton directly at a news conference back in July...
“Russia, if you’re listening, I hope you’re able to find the 30,000 emails that are missing,” (referring to Clinton’s emails from her private server)
As for why President Obama decided against responding to Russia prior to the election Government sources cited the administrations fear of starting a cyber-war as well as not wanting to appear to be interfering in the ongoing US elections.
