US congressmen demanded new sanctions against Russia based on their feeling.
No evidence given. The disinformation refers to a letter that a group of 140 House Democrats wrote to President Donald Trump to urge him to impose sanctions. democrats-foreignaffairs.house.gov/sites/democrats.foreignaffairs.house.gov/files/Russia%20Sanctions%20Letter%203.12.pdf
The disinformation argument goes that because Republicans on the House Intelligence Committee had completed a draft report (not made public yet) concluding there was no collusion or coordination between Donald Trump’s presidential campaign and Russia, the urge to impose sanctions is based on "feelings". The letter above, however, does not mention collusion, but "meddling in American democracy" and "interference in the elections".
In fact the draft report by Republicans agrees with the intelligence assessment on most other details, including that Russians did meddle in the election. apnews.com/dc7c4ec1be104801aefd46313fadb01b/Draft-GOP-report:-No-coordination-between-Trump-and-Russia
The US Intelligence Community assessment 2017 www.dni.gov/files/documents/ICA_2017_01.pdf stated that "Russian President Vladimir Putin ordered an influence campaign in 2016 aimed at the US presidential election. Russia’s goals were to undermine public faith in the US democratic process, denigrate Secretary Clinton, and harm her electability and potential presidency. We further assess Putin and the Russian Government developed a clear preference for President-elect Trump."
Special Counsel Robert Mueller's indictment states that 13 Russian citizens "from in or around 2014 to the present, knowingly and intentionally conspired with each other to defraud the United States by impairing, obstructing, and defeating the lawful functions of the government through fraud and deceit for the purpose of interfering with the U.S. political and electoral processes, including the presidential election of 2016." www.justice.gov/file/1035477/download
