Tim Scott is a Senator from South Carolina.  He's a Republican.  That's not unusual.  Most senators from the South are Republicans.  What is unusual is that senator Scott is black.  He's one of only two black senators.  The other is Cory Booker, a Democrat from New Jersey.  So, being a black, Republican Senator from South Carolina makes Scott a unique figure in modern American politics.  It also means that when he talks about race, he can grab some pretty big headlines.  That's what happened on Thursday last week.  Senator Scott stood up on the floor of the senate and talked about how he had been racially profiled by Capital Hill Police.
