Jenna Bush Hager (born November 25, 1981) is an American teacher, author, and journalist.
 She is the younger of the fraternal twin daughters of the 43rd U.S. President George W. Bush and former First Lady Laura Bush, and a granddaughter of the 41st U.S. President George H. W. Bush and former First Lady Barbara Bush.
 She and her sister Barbara were the first twin children of a U.S. president.
 Hager is an author, an editor-at-large for "Southern Living" magazine, and correspondent for NBC News.
The Society of Book and Snake (incorporated as the Stone Trust Corporation) is the fourth oldest secret society at Yale University and was the first society to induct women into its delegation.
 Book and Snake was founded at the Sheffield Scientific School in 1863 as a three-year society bearing the Greek letters Sigma Delta Chi.
 As other "Sheff" societies, it was once residential and maintained a separate residential "cloister" at 1 Hillhouse Ave, which was built in 1888 and deeded to Yale after the institution of the residential college system.
 Members who lived in the society residence, or "Cloister", become the Cloister Club.
 Today, the building is the Yale University Provost's Office.
 A plaque honoring the society can be found on the first floor of the building.
 The Book and Snake emblem is a book surrounded by the ouroboros.
The Chicken Kiev speech is the nickname for a speech given by the United States president George H. W. Bush in Kiev, Ukraine, on August 1, 1991, months before a December referendum in which Ukrainians voted to withdraw from the Soviet Union, in which Bush cautioned against "suicidal nationalism".
 The speech was written by Condoleezza Rice—later Secretary of State under President George W. Bush—when she was in charge of Soviet and Eastern European affairs for the first President Bush.
 It outraged Ukrainian nationalists and American conservatives, with the conservative "New York Times" columnist William Safire calling it the "Chicken Kiev speech" in protest at what he saw as its "colossal misjudgment".

During President Ronald Reagan's presidency, he nominated at least twelve people for various federal appellate judgeship who were not confirmed.
 In some cases, the nominations were not processed by the Democratic-controlled Senate Judiciary Committee before Reagan's presidency ended, while in other cases, nominees were rejected by the Senate Judiciary Committee or even blocked by unfriendly members of the Republican Party.
 Three of the nominees were renominated by Reagan's successor, President George H. W. Bush.
 Two of the nominees, Ferdinand Francis Fernandez and Guy G. Hurlbutt, were nominated after July 1, 1988, the traditional start date of the unofficial Thurmond Rule during a presidential election year.
 Eight of the twelve seats eventually were filled by appointees of President George H. W. Bush.
Berzelius is a secret society at Yale University named for the Swedish scientist Jöns Jakob Berzelius, considered one of the founding fathers of modern chemistry.
 Founded in 1848, 'BZ', as the society is called often, is the third oldest society at Yale and the oldest of those of the now-defunct Sheffield Scientific School, the institution which from 1854-1956 was the sciences and engineering college of Yale University.
 Berzelius became a senior society in the tradition of Skull and Bones, Scroll and Key, and Wolf's Head in 1933 when the Sheffield Scientific School was integrated into Yale University.
 Book and Snake and St. Elmo societies from Sheff, followed suit.
 Skull and Bones, founded in 1832, Scroll and Key, founded in 1841, and Wolf's Head, founded in 1883, catered to students in the Academic Department, or liberal arts college.
