The source directly confirms all key elements of the claim: (1) Niskanen Center is a 501(c)(3) with EIN 45-5308952 (stated in the info box: 'Tax ID: 45-5308952' and 'Tax-Exempt Status: 501(c)(3)'); (2) it has a 501(c)(4) lobbying arm called Niskanen Center for Public Policy (stated: 'The Niskanen Center for Public Policy is the 501(c)(4) lobbying arm of the Niskanen Center created in 2016'). The only element not explicitly confirmed in the source text is the specific EIN for the 501(c)(4) arm (47-4946572), but the source does not contradict this—it simply doesn't mention it. The core structural claims are all verified.
