The AV Club has an article on this. The article claims that Jack Posobiec and Mike Cernovich are the ones who brought these tweets up, possibly because Gunn has been so publicly critical of Trump.

Someone in the comments has pics of (which I assume are accurate, but not sure) the tweets. If those are all from Gunn, then shock-based job at the time or not, it's pretty bad. I understand that they are jokes, but I also get why Disney would want to put space between themselves and the tweets.
