Wrong, I am quoting the bits that are taking about the US Senate Special Committee on Intelligence report.

>"the findings run parallel to the conclusions of Mueller's probe"

"the findings [of the US Senate Special Committee on Intelligence] run parallel to the conclusions of Mueller's probe"

It's reconfirming that the Senate committee findings run parallel, or in other words, come to the same conclusion, as the Mueller report.
