Question: On what date was the Precision Medicine Initiative announced?

full_context: Document 1: BRAIN Initiative: The White House BRAIN Initiative (Brain Research through Advancing Innovative Neurotechnologies), is a collaborative, public-private research initiative announced by the Obama administration on April 2, 2013, with the goal of supporting the development and application of innovative technologies that can create a dynamic understanding of brain function. This activity is a Grand Challenge focused on revolutionizing our understanding of the human brain, and was developed by the White House Office of Science and Technology Policy (OSTP) as part of a broader White House Neuroscience Initiative. Inspired by the Human Genome Project, BRAIN aims to help researchers uncover the mysteries of brain disorders, such as Alzheimer's and Parkinson's diseases, depression, and traumatic brain injury (TBI).

It is founded in March 2016 by Young Woo Jang, who is now a CEO of IPMC, and Dr. Robert Hriri, the world’s renowned pioneer of the use of human stem cells to treat a range of life-threatening diseases.
Document 3: 1915 State of the Union Address: The 1915 State of the Union Address was given by Woodrow Wilson, the 28th President of the United States on Tuesday, December 7, 1915. It was given to a joint session of the 64th United States Congress, to the United States Senate and United States House of Representatives. It was given shortly before the United States entered World War I. He said these words: "The moral is, that the states of America are not hostile rivals but cooperating friends, and that their growing sense of community or interest, alike in matters political and in matters economic, is likely to give them a new significance as factors in international affairs and in the political history of the world."
Document 4: Personalized medicine: Personalized medicine, also termed precision medicine, is a medical procedure that separates patients into different groups—with medical decisions, practices, interventions and/or products being tailored to the individual patient based on their predicted response or risk of disease. The terms personalized medicine, precision medicine, stratified medicine and P4 medicine are used interchangeably to describe this concept though some authors and organisations use these expressions separately to indicate particular nuances.
Document 5: Efforts to impeach Barack Obama: During the presidency of Barack Obama, certain Republican congressmembers stated that Obama may have engaged in impeachable activity and that he might face attempts to remove him from office. Rationales offered for possible impeachment included false claims that Obama was born outside of the United States, that he allegedly allowed people to use bathrooms based on their gender identity, an alleged White House cover-up after the 2012 Benghazi attack and failure to enforce immigration laws. No list of articles of impeachment was ever drawn up and proposed to the Judiciary Committee.
Document 6: PrecisionFDA: PrecisionFDA (stylized precisionFDA) is a cloud-based next-generation DNA sequencing (NGS) data platform developed by the United States Food and Drug Administration (FDA). It was designed as part of President Barack Obama's Precision Medicine Initiative in 2015. The platform allows researchers to upload and compare data against reference genomes, bioinformatics pipelines, and genomic data. Users may also use the service to verify their genetic tests against reference genomes. The platform's code is open source and available on GitHub.
Document 7: Precision Medicine Initiative: The Precision Medicine Initiative is a research project created by Barack Obama in 2015 with $215 million in funding that aims to make advances in tailoring medical care to the individual. The project aims to collect genetic and health data from one million subjects. The initiative was announced during the 2015 State of the Union Address and is advised by Verily Life Sciences.
Document 8: 2007 State of the Union Address: The 2007 State of the Union address was a speech given by United States President George W. Bush on Tuesday, January 23, 2007, at 9:13 P.M. EST. The speech was given in front of a joint session of Congress, presided over by Speaker of the House of Representatives Nancy Pelosi and Vice President Dick Cheney in his capacity as President of the Senate. It was the first address to a Democratic-controlled Congress since 1994.
Document 9: 2016 State of the Union Address: The 2016 State of the Union address was given by the 44th United States President Barack Obama on Tuesday, January 12, 2016, in the chamber of the United States House of Representatives. It was addressed to the 114th United States Congress. It was the first State of the Union address with Paul Ryan as Speaker of the House of Representatives. It was the last State of the Union Address of Obama's presidency; no U.S. president since Gerald Ford has given a final State of the Union address at the end of his term. Obama's presidency ended on January 20, 2017.
Document 10: 2015 State of the Union Address: The 2015 State of the Union Address was given by the 44th United States President, Barack Obama, on Tuesday, January 20, 2015, in the chamber of the United States House of Representatives. Following recent tradition, Speaker of the House John Boehner sent a letter on December 19, 2014, formally inviting President Obama to speak (despite a proposal from some conservatives that House Republicans withhold the invitation in retaliation for Obama's executive actions on immigration reform). It was addressed to the 114th United States Congress. The State of the Union Address was broadcast on various television and radio stations and webcast from the White House. Webcasts were also provided by other sponsors, including a webcast from the U.S. Republican Party.
Document 11: Human Connectome Project: The Human Connectome Project (HCP) is a five-year project sponsored by sixteen components of the National Institutes of Health, split between two consortia of research institutions. The project was launched in July 2009 as the first of three Grand Challenges of the NIH's Blueprint for Neuroscience Research. On September 15, 2010, the NIH announced that it would award two grants: $30 million over five years to a consortium led by Washington University in Saint Louis and the University of Minnesota, with strong contributions from Oxford University (FMRIB) and $8.5 million over three years to a consortium led by Harvard University, Massachusetts General Hospital and the University of California Los Angeles.
Document 12: A New Beginning: "A New Beginning" is the name of a speech delivered by United States President Barack Obama on 4 June 2009, from the Major Reception Hall at Cairo University in Egypt.

White House Press Secretary Jay Carney confirmed the president's attendance later that day.
Document 14: Precision medicine: Precision medicine (PM) is a medical model that proposes the customization of healthcare, with medical decisions, practices, or products being tailored to the individual patient. In this model, diagnostic testing is often employed for selecting appropriate and optimal therapies based on the context of a patient’s genetic content or other molecular or cellular analysis. Tools employed in precision medicine can include molecular diagnostics, imaging, and analytics.
Document 15: Yves A. Lussier: Yves A. Lussier, M.D., Professional Engineer, is a physician-scientist conducting research in Precision medicine, Translational bioinformatics and Personal Genomics. As a co-founder of Purkinje, he pioneered the commercial use of controlled medical vocabulary organized as directed semantic networks in electronic medical records (1st clinical ontology available commercially), as well as Pen computing for clinicians. He was invited to the White House Precision Medicine Initiative summit.
