 There were some important firsts for the RNC after day one's slew of familiar faces, Senators Katie Britt, Tim Scott, and Marsha Blackburn, Representative Marjorie Taylor Greene. I would have been surprised if she hadn't been there. She has been a very staunch Trump supporter. I don't like her much, but she's been staunch. The most remarkable was Sean O'Brien, president of the International Brotherhood of Teamsters.
