Fox News Contributor Byron York is claiming that it was Lt. Colonel Alexander Vindman who was behind the impeachment push and not the alleged “whistleblower.”

York makes these revelations in his new book  “Obsession: Inside the Washington Establishment’s Never-Ending War on Trump.”

York told Laura Ingraham, “It didn’t take a real rocket scientist that the source of this, the original source of this, was Lt. Col. Vindman.”

According to Fox News:

“If you remember early on in the Ukraine matter, the Democrats said they wanted the whistleblower to testify, and then they changed their mind and they didn’t want the whistleblower to testify and they began to shut off any Republican attempts to find out who the whistleblower was,” he said.

The Washington Examiner chief political correspondent asked, “So the question is if the whistleblower wasn’t in the White House, how did he learn what was going on?”

He points out Vindman was one of several people who listened to Trump’s call with Ukrainian President Volodymyr Zelensky, “but [Vindman] was the only one who was disturbed by what took place. He was the only one who thought there was a problem there.”

…

York also claimed former Special Counsel Robert Mueller’s team, formed in May of 2017, knew early on there wasn’t evidence for Trump-Russia collusion but continued to investigate.

York did state that Republicans had a hard time questioning Vindman because of his “decorated” military career, even though they knew he was the origin and Schiff’s source.
