In March 2019, Senator Ted Cruz (R-TX) introduced a proposal to establish a new, nationwide federal tax-credit scholarship program. Representative Bradley Byrne (R-AL) introduced a companion proposal in the House. Although Congress' support of school choice is praiseworthy, a federal tax-credit scholarship program poses a threat to education choice in the states, and undermines the goal of a streamlined federal tax code. The federal government does not have the constitutional authority to create such a program, which would establish massive new federal spending and would likely subject private schools to future regulations from an Administration and Congress less friendly to education choice. State governments do have the constitutional authority to enact school choice policies, and have been the catalyst for the impressive growth in school choice over the past two decades in the United States.
