You are right about Fox news. I’m sure they despise Trump but they are being a little skittish right now about going after him.
Maybe they’re afraid he’ll sue them.
Or do nasty tweets about him.
Heck, even Carson had to admit that the report had come to the Cruz campaign via CNN from Carson's own staff. Did Greta ever walk back her enthusiasm for Trump's accusation of Cruz? I don't believe so.
The damage to Cruz was done, and she won't undo it because she is afraid of Trump. She doesn't care enough about the Truth to stick her neck out where it belongs--for Cruz.
