Nbc news has learned that president obama personally warned President Trump against hiring Michael Flynn as National Security adviser. That warning came at the white house less than 48 hours after the november election. The revelation comes on the same day that former acting attorney general sally yates testified about the events that led up to flynns eventually firing. Blayne alexander is on capitol hill to try to break it down for us. Hi, blayne. Reporter and doreen, you mentioned that november meeting. Its certainly one that we all remember well.

Were talking a spy. We havent seen anything like this ever before. Reporter another question, how strenuous was president obamas warning . This as former acting attorney general sally yates tftd testified on capitol hill, telling senators she warned the white house that flynn had lied about his ties to russia. Not only do we believe that the russians knew this, but that they likely had proof of this information, and that created a compromise situation. A situation where the National Security adviser essentially could be blackmailed by the russians. Reporter following that conversation, it took more than two weeks for President Trump to demand flynns resignation. Now the russia issues aside, youll remember that sally yates and President Trump have a rather rocky history. Youll remember that yates was acting attorney general under the president. She was a holdover from the obama a to enforce President Trumps travel ban back in january, he fired her just ten days into her stint as acting attorney general. Chris . Thank you, blayne. The d. C.
