outcome of this investigation. and you also have reporting about mcfarlane the former trump official about what she knew about michael flynn contact with the russian ambassador. what did you learn? reporter: yeah, that s right. she had testified before the senate foreign relations committee as part of her nomination to be ambassador to singapore. when he was asked in written correspondence whether she knew about any conversations between michael flynn and the russian ambassador kislyak, she said she was not aware of that. it turns out that it shows a senior official did have conversations with michael flynn about kislyak and the issue of russian sanctions and we learned that senior official was katie mcfarlane. now i ask asked senator bob corker what this does for her nomination. here s what he said. if she did testify inappropriately, obviously that s a big, big problem.
