Today, Trump blames Obama for Russia meddling.
A. Obama imposed sanctions against Russia in response.
B. Obama booted Russian diplomats in response.

Obama, being the do-gooder that he is, didn't do more for fear that he would be accused of interfering with 2016 election.
But, people need to stay focused because this is just a diversion.
Trump has been president for over a year, and he has done nothing on Russia. He completely denies what the intelligence community unanimously agrees on -- that Russia meddled in our 2016 election. (https://www.cnn.com/2018/02/13/politics/intelligence-chiefs-russia-2018-elections-target/index.html)
But, Trump has done even worse than nothing. Congress passed legislation to prevent the president from rolling back Obama's Russian sanctions (https://www.reuters.com/article/us-usa-russia-sanctions/trump-administration-holds-off-on-new-russia-sanctions-despite-law-idUSKBN1FI2V7).
But, Trump simply ignored the legislation, even though he signed it!
At some point, you really need to ask why there is so much deference to Russia and so much animosity towards our own intelligence services that have been warning about the Russia threat since at least 2016?
At a recent Congressional hearing, those intelligence agencies re-confirmed Russia meddling, with an added qualification that the evidence is incontrovertible (http://thehill.com/policy/national-security/374352-mcmaster-evidence-is-incontrovertible-that-russia-interfered-in-2016).
Nobody is saying anything about if it was done in favor/against a candidate or if there was collusion. And, indictments handed out so far impact a few people associated with the Trump campaign/administration (Paul Manafort, Michael Flynn, Rick Gates and George Papadopoulos). https://www.cnn.com/2017/12/04/politics/whos-charged-russia-investigation/index.html
And recently 13 Russians. https://www.npr.org/2018/02/16/586500591/grand-jury-indicts-russians-linked-to-interference-in-2016-election
But, there hasn't been any evidence, thus far, of collusion by a presidential candidate. The only one obsessing about collusion is the man sitting in our White House. Why is that?
