2017, 2018, and 2019 — Democrat members of Congress stated as fact on Twitter that they had evidence that Trump colluded with Russia, which fueled the leftist narrative that the election was illegitimate.
Their claims were “in dispute” by other members of Congress, as well as members of the Trump administration and the president, but Twitter never flagged them as such, as it did with Trump’s recent tweets.
On April 21, 2019, House Intelligence Committee Chairman Adam Schiff (D-CA) tweeted that special counsel Robert Mueller “did find evidence of collusion.”
