evidence: President Donald Trump retweeted a post by comedian Terrence K. Williams that wrongly purports to show Rep. Ilhan Omar "partying" and "celebrating" on the anniversary of the 9/11 terrorist attacks. The video was actually from a Congressional Black Caucus event on Sept. 13. [...] The video of Omar dancing was originally posted by Adam Green, co-founder of the Progressive Change Campaign Committee. A tweet from BoldProgressives.org confirmed the video was posted by Green from a CBC event on Sept. 13, and called Trump’s tweet "an abhorrent lie." Our co-founder @AdamGreen posted this video from a CBC event on Sept 13, and @IlhanMN retweeted it. Today @realDonaldTrump tweeted that she "partied on the anniversary of 9/11." This is an abhorrent lie that endangers a Member of Congress. Twitter must remove Trump's Tweet now. https://t.co/zzeb1dXTzc — BoldProgressives.org (@BoldProgressive) September 18, 2019
