The High National Grasslands is owned by the United States and is located in the center of a large western state. Acting pursuant to a federal statute authorizing such action, the United States Bureau of Land Management leased the grazing rights in the High National Grasslands to ranchers located nearby. Grazingland Company owns a vast amount of rangeland adjacent to the High National Grasslands and leases its land for livestock-grazing purposes to the same ranchers, but at prices higher than those charged by the Bureau. Grazingland Company sued the Bureau in an appropriate federal district court to restrain the Bureau from competing with that company by leasing the High National Grasslands. Which of the following constitutional provisions may most easily and directly be used to justify the federal statute authorizing this leasing program of the Bureau of Land Management?
