Q: Question: How big was Yale's endowment the year that George W. Bush was elected President of the USA? Passage 1:The Andres Bonifacio-class frigates were passed to the Philippine Navy with fewer weapons aboard than they had had during their U.S. Navy and U.S. Coast guard careers and with old surface search radars installed. The Philippine Navy addressed these shortfalls through modernization programs. In Philippine service, Diego Silang retained her South Vietnamese armament, consisting of a single Mark 12 5"/38 caliber (127-mm) gun, a dual-purpose weapon capable of anti-surface and anti-air fire, mounted in a Mark 30 Mod 0 enclosed base ring with a range of up to yards; two twin Mark 1 Bofors 40mm anti-aircraft gun mounts, four Mk. 4 single 20-millimeter Oerlikon anti-aircraft gun mounts, four M2 Browning .50-caliber (12.7-millimeter) general-purpose machine guns, and two 81-mm mortars. However, in 1979 Hatch and Kirk, Inc., added a helicopter deck aft which could accommodate a Philippine Navy MBB Bo 105C helicopter for utility, scouting, and maritime patrol purposes, although the ship had no capability to refuel or otherwise support visiting helicopters. The Sperry SPS-53 surface search and navigation radar also was installed, replacing the AN/SPS-23 radar, although the ship retained both its AN/SPS-29D air search radar and its Mark 26 Mod 1 Fire Control Radar System. The Philippine Navy made plans to equip Diego Silang and her sister ships with new radar systems and long-range BGM-84 Harpoon anti-ship cruise missiles, but this upgrade did not materialize due to the worsening political and economic crisis in the Philippines in the mid-1980s.
Passage 2:Bates was a law clerk for Judge Roszel Cathcart Thomsen of the United States District Court for the District of Maryland from 1976 to 1977 and was an associate at Steptoe & Johnson from 1977 to 1980. He served as an Assistant United States Attorney for the District of Columbia from 1980 to 1987, and was Chief of the Civil Division of the United States Attorney's Office from 1987 to 1997. Bates was on detail as Deputy Independent Counsel for the Whitewater investigation from 1995 to mid-1997. In 1998, he joined the Washington, D.C. law firm of Miller & Chevalier, where he was Chair of the Government Contracts/Litigation Department and a member of the Executive Committee. From September 1995 until leaving in March 1997, Bates worked as Deputy Independent Counsel for Kenneth Starr and the Independent Counsel's office during the investigation into President Bill Clinton.
Passage 3:Kavanaugh graduated from Yale University, where he joined Delta Kappa Epsilon fraternity. After graduating from Yale Law School, he began his career as a law clerk and then a postgraduate fellow working under Judge Ken Starr. After Starr left the D.C. Circuit to take the position as head of the Office of Independent Counsel, Kavanaugh followed and assisted him with various investigations concerning President Bill Clinton, including the drafting of the Starr Report, which urged Clinton's impeachment. After the 2000 U.S. presidential election (in which he worked for the George W. Bush campaign in the Florida recount), he joined the administration as White House Staff Secretary and was a central figure in its efforts to identify and confirm judicial nominees. Kavanaugh was nominated to the U.S. Court of Appeals for the D.C. Circuit by President Bush in 2003. His confirmation hearings were contentious; they stalled for three years over charges of partisanship. He was ultimately confirmed to the D.C. Circuit in May 2006 after a series of negotiations between Democratic and Republican U.S. Senators. An evaluation of Kavanaugh's appellate court decisions in four separate public policy areas was performed by two law professors for the Washington Post. It found he had the most conservative overall voting record on the D.C. Court between 2003 and 2018.
