It appears that Trump’s group was invited by long time friend Franklin Graham Here is a link to his group Sumaritan’s Purse. Trump, Palins, Greta all have been big supporters of the organization
Thanks HM!
I know that Greta has supported SP for quite a while and I’ve seen her shows where she’s had Pastor Graham on and also showing her on location passing out the boxes they make. I’ve read that President-elect Trump has been friends with FG and has contributed to SP for a long time, but like with his other donations and generous help I think he likes to keep it somewhat quiet and not boast about it (he’s humble that way).
