According to the special counsel investigation’s Mueller Report (officially named “Report on the Investigation into Russian Interference in the 2016 Presidential Election”), the first method of Russian interference used the Internet Research Agency (IRA), a Kremlin-linked troll farm, to wage “a social media campaign that favored presidential candidate Donald J. Trump and disparaged presidential candidate Hillary Clinton”. The Internet Research Agency also sought to “provoke and amplify political and social discord in the United States”.
It helps if you fight dirty.
