According to the NY Post's Page Six, ABC is said to be fuming mad because Good Morning America host Michael Strahan refused to come home from his vacation to cover Hurrican Harvey. 

A source told Page Six: “ABC News asked Strahan to come home from his vacation. He’s from Houston. But he refused and is still floating around on a yacht in Greece somewhere. ABC is really upset with him.”

So let's get this straight, the ABC brass is pissed that Strahan won't cut his vacation short, but they are totally fine with David Muir being on vacation? 

If I was Muir, I might update my resume, you know, just in case.
