"And in fact when I decided to just do it I said to myself, I said, “You know, this Russia thing with Trump and Russia is a made-up story, it’s an excuse by the Democrats for having lost an election that they should’ve won.”"
Trump told the world that he fired Comey for opening what has now been shown by the IG and SC Durham after a 4 year investigation to be properly predicated, if flawed. Firing Comey was an attempt by Trump to avoid accountability for what he and his campaign did, along with destruction of evidence, lying under oath, and 11 other counts of obstruction of justice by Trump identified by SC Robert Muller.It turns out Trump's campaign did meet with Russians and lied about it; Trump did had business in Russia he lied about; his campaign manager did meet with a Russian spy to discuss handing over dirt on his opponent; Russians did hack the Democrats and distribute the data; Trump did ask them publicly to hack his opponent in exchange for relaxed sanctions; and his campaign was knowingly sharing data with a Russian intelligence officer. So of course an investigation was opened into his campaign and their ties to Russia.
