It's in the very first paragraph in the article
Donald Trump's campaign is going all out to win delegates in Nevada, offering to cover transportation and lodging costs for Nevada supporters who travel to Reno in mid May to participate in delegate elections.
It's reported that way...
Oh, I read that sentence you posted. My point is that the quote from the director doesn’t confirm this.
I looked to see if the email and/or offer allegedly sent out was included in this *report*, but I couldn’t find it.
