Putin told me they didn't do it. And I believe them.
(snicker)
Simply put, the Russians know the USA is ripe for more chaos and they'd love the chance to do it. But I'm not sure what being caught red handed (TRIPLE PUN COMBOOOOO) does here. Trump actually still likes Russia, therefore, the Party of Trump likes Russia. And they said all the election stuff was a hoax. This feels like Russia losing one of their assets here. Can't say I see the logic. And no, "they didn't expect to get caught" isn't a good reason.
