A threshold legal question is whether providing to a campaign “documents and information” of the type involved here would constitute a prohibited campaign contribution. The foreign contribution ban is not limited to contributions of money. It expressly prohibits “a contribution or donation of money or other thing of value.” 52 U.S.C. § 30121(a)(1)(A), (a)(2) (emphasis added). And the term “contribution” is defined throughout the campaign-finance laws to “include[]” “any gift, subscription, loan, advance, or deposit of money or anything of value.” 52 U.S.C. § 30101(8)(A)(i) (emphasis added).
