From the Document: "The House Committee on Appropriations and Committee on Transportation and Infrastructure have separately announced that individual Members may request funding for specific transportation projects. This ends an effective ban on earmarks [hyperlink] that has been in force in the House since 2011. This Insight summarizes the new rules applicable to Member-designated transportation projects and points out certain matters that appear to remain unclear. A congressional designation, the formal term for an earmark [hyperlink], is a provision in a law or report language that has four basic attributes. It  is included at the request of a Member, Delegate, Commissioner, or Senator;  recommends a specific amount of discretionary budget authority, credit authority, or other budget authority;  is for an identifiable entity or targeted to a state, locality, or congressional district; and  is not awarded through a statutory or administrative formula-driven or competitive award process."
