Congress. The Washington Post reported in December 2013 that, since Puerto Ricans became US citizens in 1917, they have "been divided over their relationship with the mainland" on whether to become a US state, become independent, or a self-governing territory under US control. 2017 status referendum The previous plebiscites provided voters with three options: statehood, free association, and independence. The 2017 referendum offered three options: Statehood, Commonwealth and Independence/Free Association. If the majority vote for the latter, a second vote will be held to determine the preference: full independence as a nation or associated free state status with independence but with a "free and voluntary political association" between Puerto Rico and the United States. The White House Task Force on Puerto Rico offers the following specifics: "Free Association is a type of independence. A compact of Free Association would establish a mutual agreement that would recognize that the United States and Puerto Rico are closely linked in specific ways as detailed in the compact. Compacts of this sort are based on the national sovereignty of each country, and either nation can unilaterally terminate the association." The content of the Compact of Free Association might cover topics such as the role of the US military in Puerto Rico, the use of the U.S. currency, free trade between the two entities, and whether Puerto Ricans would be U.S. citizens. Former Governor Ricardo Rosselló was strongly in favor of statehood to help develop the economy and help to "solve our 500-year-old colonial dilemma ... Colonialism is not an option . ... It's a civil rights issue ... 3.5 million citizens seeking an absolute democracy," he told the news media. Benefits of statehood include an additional $10 billion per year in federal funds, the right to vote in presidential elections, higher Social Security and Medicare benefits, and a right for its government agencies and municipalities to file for bankruptcy. The latter is currently prohibited. At approximately the same time as the referendum, Puerto Rico's legislators voted on a bill that allows the Governor to draft a state constitution and hold elections to choose senators and representatives to the federal Congress. Regardless of the outcome of the 2017 referendum and the bill, action by the United States Congress will be necessary to implement changes to the status of Puerto Rico under the Territorial Clause of the United States Constitution.
