 If you're hearing a lot of noise behind me today, it's because I'm speaking to you from the Republican National Convention in Milwaukee, Wisconsin. Sitting beside me is BBC reporter Mike Wendling. Hi, Mike. Hello, hello. Mike, there is the same carnival kind of atmosphere that there always is at conventions. Thousands of people, long security lines, road cordons and so on. But there is a certain tension as well because of this attempt to assassinate the former president just a couple of days ago.
