I wonder if the Pastor knows any of the familiar-named Florida folks than run "missing children's charities"...like D&CM, MB, JD/and his poker runs and souped-up "missing kids" pickup truck or the guy who wants to build a memorial walkway in the swamp.
Even if Miss A is being supported by "in kind" benefits, she may want to be careful not to exceed the allowable limit and then be responsible for "reportable" donations.
My guess, the pastor was given the donation with "strings attached" and will start his own "charity" not having to do with children. He will then hire Miss A, at a ridiculously high annual income, which will be legal...and then keep the rest for his other "needy" parishioners and perhaps pay himself a nice salary to administrate the charity.
The good news is if tax fraud is going on, the wittle preacher and his "guest" will be indicted on federal charges.
