Notice the double standard.
NYT or Hillary makes claims and no demands for sources or facts backing up said claims.
Trump says something and they demand he show his cards.
OMGosh! Exactly! Hell’s bells, Trump has nothing to work with either. He is throwing their own stories back at them, (thankfully) but in the absence of help from the Hill investigating for him, then doing so is his only weapon.
But, even those stories are completely HEADLESS, full of “sources say”.
