imposed tough new safety standards for animal feed manufacturers, a move widely supported in the market to retain public confidence. She took a tough line against cultivation of genetically modified organisms (GMOs) in Germany but received praise from commodity traders when she supported imports of GMOs approved in the United States and South America to secure German supplies of soybeans for animal feed. Meanwhile, she repeatedly expressed concern that outside financial investment in agricultural commodity markets distorts prices, instead calling for more transparency in commodity markets and clear visibility of the difference between futures investment by industrial food buyers and financial investors. In 2009, Aigner caused a controversy when she called for requirements to publish the names and location of recipients of Common Agricultural Policy (CAP) subsidies to be “suspended” until the implications for data protection have been assessed. In response, the European Commissioner for Agriculture and Rural Development Mariann Fischer Boel threatened Germany with legal action. Aigner has been outspoken in her criticism of Facebook, which she has said needs to do to protect its users' privacy. In September 2011, she asked all federal ministers in Germany not to use Facebook for public relations and communication. In 2010, she criticized Google over plans to give property owners a four-week deadline to stop their buildings from showing up on the company's then newly launched Street View mapping service, demanding that all requests be considered instead. Amid the German debate on the country's energy transition to an energy portfolio dominated by renewable energy, Aigner called in later 2012 for the partial nationalization of the country's electrical grid in order to ensure that high-voltage power lines required to transport green energy from offshore windfarms and other sources to the industry-heavy regions of southern Germany are built. In 2012, Aigner announced she would leave her post to return to local politics in her home state of Bavaria following the 2013 national elections, prompting speculation that she was eyeing the post of Bavarian Minister-President Horst Seehofer. Deputy Minister-President of Bavaria, 2013–2018 Following her return to Bavaria after the state's 2013 elections, Aigner was named Minister-President Horst Seehofer's deputy as well as Bavarian Minister for Economic Affairs, Media, Energy and Technology. As one of Bavaria's representatives at the Bundesrat, she served on the Committee on Cultural Affairs; the Committee on Economic Affairs; and the Committee on the Environment, Nature Protection and Reactor Safety.
