Trump was asked by reporters on Feb. 10, as he made his way to Mar-a-Lago aboard Air Force One, if he had any comment on the stories that Flynn had contacted Russian authorities and talked about the sanctions put into place by President Obama. "I don't know about that," he said. "I haven't seen it.”
According to Sally Yates, then acting attorney general, she informed the White House counsel of Flynn's misleading statements in “late January.” She said she was concerned that Flynn could be subject to blackmail by the Russians because they knew what he had discussed with the Russian ambassador and knew he was not, at least publically, revealing that.
Yates was dismissed from her job not long after when she refused to defend Trump’s immigration travel ban.
