The Russian government made extensive efforts, through hacking of email as well as information warfare, to help Donald Trump win the 2016 election. Multiple members of the Trump campaign knew of these efforts in advance. Trump himself publicly called on the Russian government to release information that would hurt Hillary Clinton and benefit him. During the course of the election, Trump's campaign chairman exchanged polling data with someone who the FBI has said has ties to Russian intelligence; Trump's son wrote "I love it!" when offered what he thought was dirt on Hillary Clinton from Russia; Trump's camp maintained an elaborate business relationship with Russians who by definition had ties to the Kremlin (because all wealthy Russians have ties to the Kremlin).
