Input: Article: 808s & Heartbreak, which features extensive use of the eponymous Roland TR-808 drum machine and contains themes of love, loneliness, and heartache, was released by Island Def Jam to capitalize on Thanksgiving weekend in November 2008. Reviews were positive, though slightly more mixed than his previous efforts. Despite this, the record's singles demonstrated outstanding chart performances. Upon its release, the lead single "Love Lockdown" debuted at number three on the Billboard Hot 100 and became a "Hot Shot Debut", while follow-up single "Heartless" performed similarly and became his second consecutive "Hot Shot Debut" by debuting at number four on the Billboard Hot 100. While it was criticized prior to release, 808s & Heartbreak had a significant effect on hip-hop music, encouraging other rappers to take more creative risks with their productions.

Input: Article: Washington, D.C. is often mentioned as a candidate for statehood. In Federalist No. 43 of The Federalist Papers, James Madison considered the implications of the definition of the "seat of government" found in the United States Constitution. Although he noted potential conflicts of interest, and the need for a "municipal legislature for local purposes," Madison did not address the district's role in national voting. Legal scholars disagree on whether a simple act of Congress can admit the District as a state, due to its status as the seat of government of the United States, which Article I, Section 8 of the Constitution requires to be under the exclusive jurisdiction of Congress; depending on the interpretation of this text, admission of the full District as a state may require a Constitutional amendment, which is much more difficult to enact. However, the Constitution does not set a minimum size for the District. Its size has already changed once before, when Virginia reclaimed the portion of the District south of the Potomac. So the constitutional requirement for a federal district can be satisfied by reducing its size to the small central core of government buildings and monuments, giving the rest of the territory to the new state.

Now answer this question: What caused the size of Washington, D.C. to change?

Output:
Virginia reclaimed the portion of the District south of the Potomac
