Georgia House Bill 51: House Bill 51 (full title: Postsecondary institutions; reporting and investigation of certain crimes by officials and employees; provide manner) is a bill introduced into the Georgia House of Representatives which would limit the ability of college campuses in Georgia to investigate alleged sex crimes committed on campus.  For example, it would effectively sidestep the common university practice of holding so-called "Title IX hearings" to decide whether to discipline a student accused of sexual assault.  Instead, the bill would require some university employees to report possible felonies to law enforcement.  The bill was introduced by Representative Earl Ehrhart (R-Powder Springs) on January 11, 2017, and was passed by the House of Representatives on March 1, 2017, in a 115-55 vote.  On March 24, the Georgia State Senate Judiciary Committee tabled the bill, On March 28, Ehrhart replaced a part of Senate Bill 71 that pertained to health savings accounts with language from House Bill 51 in an effort to get it passed.  Nevertheless, this bill, like HB51, failed to receive final approval before the state legislature ended its work for the year.  However, it can still be considered for passage in next year's session.

John Y. Brown (politician, born 1835): John Young Brown (June 28, 1835January 11, 1904) was a politician from the U.S. state of Kentucky.  He represented the state in the United States House of Representatives and served as its 31st governor.  Brown was elected to the House of Representatives for three non-consecutive terms, each of which was marred by controversy.  He was first elected in 1859, despite his own protests that he was not yet twenty-five years old; the for serving in the legislature.  The voters of his district elected him anyway, but he was not allowed to take his seat until the Congress' second session, after he was of legal age to serve.  After moving to Henderson, Kentucky, Brown was elected from that district in 1866.  On this occasion, he was denied his seat because of alleged disloyalty to the Union during the Civil War.  Voters in his district refused to elect another representative, and the seat remained vacant throughout the term to which Brown was elected.  After an unsuccessful gubernatorial bid in 1871, Brown was again elected to the House in 1872 and served three consecutive terms.  During his final term, he was officially censured for delivering a speech excoriating Massachusetts Representative Benjamin F. Butler.  The censure was later expunged from the congressional record.

Martin Gang: Martin Gang ((1901--) 12, 1901 – (1998--) 29, 1998 ) was an American lawyer who fought against the 1940s and 1950s Hollywood blacklist.  From 1931 to his death, he was a partner in the American law firm now known as Gang, Tyre, Ramer, and Brown (originally Gang, Kopp, and Brown).  In the 1950s, Gang was known for providing legal representation to movie industry workers who cooperated with the House Un-American Activities Committee and was a leading member of the American Jewish Committee.  He was portrayed in the 1991 movie "Guilty by Suspicion".  One of the McCarthy era's most frequent "clearance" lawyers in Hollywood, Gang developed methods for ensuring that admitted but publicly repentant former communists could avoid studio blacklists and continue working in Hollywood.  He counseled his clients to cooperate with the House Committee on Un-American Activities (HUAC), to admit their connection to communism, to fully repudiate their former beliefs, and to tell HUAC what they knew about former friends, colleagues, and acquaintances who were involved in communist groups.  Counseling clients to "name names" is without question the most controversial and puzzling aspect of Gang's career.  How could a lifelong liberal and founding member of the National Lawyer's Guild have been involved with facilitating and legitimatizing the work of HUAC?  Gang himself thought he was merely zealously representing the interests of his client who simply wanted to keep working.  HUAC already had the names so none of the people he counseled to cooperate with HUAC were damaging anyone who wasn't already implicated.  But to cooperate with a witch hunt and to legitimize the witch hunters by cooperating with them is a bizarre legacy for a man of Martin Gang's stature and liberal bona fides.
