Sen. Thom Tillis (R-NC) addresses the history of U.S. interference in foreign elections at Thursday's hearing on possible Russian interference in the 2016 U.S. presidential election. Tillis said the U.S. is living in a "big glass house," responding to <a href="http://www.realclearpolitics.com/video/2017/01/05/graham_at_russia_hearing_it_is_time_not_to_throw_pebbles_but_to_throw_rocks.html">Sen. Graham's "rocks" comment</a>, and noted that the U.S. has "been involved in one way or another" in at least 81 different foreign elections since the end of World War II. <blockquote>SEN. TILLIS: Director Clapper, I'm going to spend most of my time reflecting on the comments that you have made. The glass house is comment is something that I think is very important. There has been research done by professors up at Carnegie Mellon that has estimated that the United States has been involved in one way or another in 81 different elections since World War II. That doesn't include coupes or the regime changes, some tangible evidence where we have tried to affect an outcome to our purpose. Russia has done it some 36 times. In fact, when Russia was apparently was trying to influence our elections, we had the Israelis accusing us of trying to influence their election. I'm not here to talk about that but I am here to say that we live in a big glass house and there are a lot of rocks to throw and I think that is consistent with what you said on other matters.</blockquote>
