“”Keeping his fundraiser quiet” means not yelling to the media “Look at me!!!! I’m raising money for the vets!!!””
He couldn’t hold a fundraiser without publicizing it.
Trump is the biggest draw in the country right now, and he’s using his celebrity for the vet’s benefit, for free, instead of letting Fox News benefit by doubling their debate audience.
Of all the complaints about Trump, complaining about him donating his name and time to raising money for wounded vets has to rank as the most petty.
I do not understand this kind of thinking. Maybe it is way past my bedtime. : )
