Collin Rugg✓@CollinRugg NEW: LA Mayor Karen Bass says she’s investigating why she was allowed to go on a trip to Ghana days before the LA fires. Investigating someone else for something you did is wild. Bass: That level of preparation really didn't happen. So it didn't reach that level to me. No one said you shouldn't have gone on a trip. Reporter: Why didn't it happen? Bass: I don’t know. That’s what we are investigating.
