#OnThisDay, President Herbert Hoover signed into law a bill that designated the “Star-Spangled Banner” as the National Anthem of the United States. Representative John Linthicum of Maryland introduced the legislation, secured a hearing with the Judiciary Committee, and implored his colleagues to attend with a speech that claimed the nation "needed a national song to give expression to its patriotism.” Please enjoy this rendition of the #StarSpangledBanner by our own U.S. Army Voices. #nationalan
