Links between Trump associates and Russian officials

Since Donald Trump was a 2016 candidate for the office of President of the United States, multiple suspicious links between Trump associates and Russian officials were discovered by the FBI, a special counsel investigation, and several United States congressional committees, as part of their investigations into Russian interference in the 2016 United States elections. Following intelligence reports about the Russian interference, Trump and some of his campaign members, business partners, administration nominees, and family members were subjected to intense scrutiny to determine whether they had improper dealings during their contacts with Russian officials.
