From the Document: "Bulgaria is a Southeastern European country located along the Black Sea. After decades of single-party communist rule and a turbulent transition period during the 1990s, Bulgaria joined NATO in 2004 and the European Union (EU) in 2007. The United States cooperates with Bulgaria on a range of security issues but also has raised concerns over corruption and the rule of law. Bulgaria has been in a political stalemate for most of 2021. Parliamentary elections in April 2021 and repeat elections in July 2021 did not result in the formation of a government. A third parliamentary election is scheduled for November 14, 2021, along with presidential elections."
