Michael Flynn had contact with Russian government officials, took money from a Russian company (which he didn't divulge on his employment contract with the Trump administration). He lied about his contact with Russians and was fired from his job as National Security Adviser. He is now seeking immunity from prosecution in exchange for his testimony.
According to US intelligence agencies Paul Manafort, Trump campaign director for most of the campaign, had regular contacts with Russian officials during the campaign.

Manafort quit the campaign after he learned the FBI was investigating whether or not US firms (including Manafort's firm) were involved in political corruption in Ukraine.
