Trump has been objectifying women for decades. He often attacks women's appearance because that is the only value he holds for them. He did it again in this tweet as well. 

Sexism and misogyny are not just "politically correct no nos" It has real and lasting consequences for women. What message do you think it sends to girls and women when the President of the United States only regards them as props for his viewing pleasure? Then again, since you're defending him, I am guessing you view women in the same way he does.

In addition, they were not trying to "buddy up trump off camera" they were working, trying to get him to interview with them.
