A key talking point in the theory that Donald Trump and the Russians conspired in the 2016 election is the allegation that last summer, during the Republican convention, the Trump campaign changed the GOP platform to weaken its stance on Russia's aggression in Ukraine.

It's been cited many, many times. The only problem is, it's all wrong.

The wildest expression of the theory came, as it often does, from MSNBC's Rachel Maddow, who told viewers on March 8 that "something weird" happened to the GOP platform on "that Ukraine and Russia thing" when the Trump team "jumped right up on that and they insisted that that plank only, that one, had to be taken out, that language could not stand."
