The Ukraine conspiracy theory that captured President Trump’s imagination and put him in jeopardy of impeachment is more complex and probably a bit older than you think.

With the Mueller Report out of the way, conservative pundits and Trump allies have tried to discredit the Russia investigation and its origins, an effort that culminated in an investigation launched by Attorney General William Barr.
