It strikes at the very heart of our system of government, which is what the identity of this country is built on.
Let the record speak for itself.

That doesn't mean I'm a fan of its system of government. I am a libertarian, not a big D Democrat or a small d democrat.
How do you suggest speech like Barack Obama's to Macron and the people of the UK be curtailed? Internet filters?
And Russia did not even endorse anyone in the 2016 race. The only problem you have is with public access to Hillary Clinton's Goldman Sachs transcripts. Sometimes, whenever I think I might be too cynical, I read something like this and remember I'm not nearly cynical enough.
