I can definitely see that she may have not got clearance.
We know Vince McMahon came out and said he doesn't want to see politics in football, with his XFL 2020 conference. So i think it's safe to say that he probably doesn't want politics in the WWE either.

My own 2 cents - Good on Lita - She should stand up for what she thinks is right, and the women's royal rumble is a good place to do it.

It's not like they can fire her!
