I watched a interview with Hillary on Ellen Show.
Hillary was talking about her granddaughter. Ellen asked what she called Hillary
Hillary said on the show :
She’s got a couple of words. I’m waiting to see what she wants to call me. If I like it, I’ll say “yeah that’s a good one”. If I don’t, then I’m gonna have to work on what else can she call me.
I thought that the last sentence was supposed to be like I'm gonna have to work on what else she can call me. Because 'what else she can call me' is not a question. So, I thought she said it grammatically wrong. But I'm not sure if it is her slight mistake.
You could watch it at 3:53 https://www.youtube.com/watch?v=RihhE7Qgkww&t=3m50s
