Thanks.

Greg is absolutely Trump's puppet, because it's ratings gold to be one. I'll give you a behind-the-scenes related story, from someone very close to the situation:

Greg was pretty NeverTrump until Trump won in 2016, and his weekend show at the time suffered greatly because of it. Jeanine Pirro's Trump-sycophantic show was on right before his, and was pulling in crazy strong numbers.

He noticed and "adjusted". Look where he is now.
