OTOH, aren't a lot of his records inaccessible as well. Have we seen his tax records even? I know a lot of other documentation has not been made available.
In the 6 years prior to running for office he gave 1% in donations (give or take 1/10th of %)
It wasn't until the last 2 years when he was running for POTUS, and that he made big money from his books, that he gave about 4% and 6%.
Dang he's generous (with other peoples money).
