The US left took those Trump-Russia files as gospel, even though it turned out that the whole thing was most probably a set-up.
As such, the same US left now saying that one shouldn't take those Twitter files seriously is quite disingenuous, if anything, the Twitter files seem more real than any of that Trump-Russia fiasco.
The Trump Russia files were exposed as a 'work in progress' investigation from a former spy that wasn't supposed to be leaked yet. Stuff he was still researching. If you think the "US left" took them as "gospel", you may be consuming too much propaganda. Nobody thinks the Twitter files were fake, they just didn't reveal anything as damning as claimed. Is it surprising that the president's team asked them to remove (illegal) stolen pictures of his son's dick? Seems expected and reasonable.
