Mayhap he wants to ask Cruz to be his VP and wants to make sure he is eligible.
Yep, and Trump knows the best way to vet his future VP pick is to go on MSM TV shows telling the whole world that you think he is not eligible for that same job, but you hope that you are wrong and are rooting for him, just before a critical primary.
Trump has a heart of Gold being so defensive of Cruz.
And his being worried about the GOP if things didn't work out for them. .
Having publicly said he believes Cruz to be ineligible then in order to ask Cruz to be his VP then Trump would have to admit he was wrong. When has that ever happened?
