Problem: The Raiders were eliminated from playoff contention with a loss by Miami the previous day, but traveled to Philadelphia for a Christmas night game against the NFL-best 12-2 Eagles. After the Eagles punted on their first drive, Oakland drove to the Eagles' 42, but failed convert on fourth down. Eagles quarterback Nick Foles, playing for the injured Carson Wentz, then led the team down the field and opened the scoring on a 17-yard touchdown pass to Jay Ajayi to put the home team up 7-0. After the teams traded punts, Carr threw a 63-yard touchdown pass to Amari Cooper to tie the game up early in the second quarter. Philadelphia found themselves in scoring position late in the half, but rookie kicker Jake Elliott missed a 33-yard try right before the half leaving the game tied at seven. Starting the second half, the Raiders moved into Philly's red zone, but were held out of the end zone and forced to settle for a field goal by Giorgio Tavecchio to take a 10-7 lead. On the Raiders' next possession, Carr was intercepted by CB Patrick Robinson ending the Raiders promising drive. Two plays later, Ajayi fumbled and the Raiders took over. However, on the first offensive play for the Raiders, Marshawn Lynch to lost his first fumble of the season and resulting in three turnovers in four plays. The Eagles used that possession to kick another field goal to tie things up at 10-each. Defensive efforts and poor offense by both teams caused them to trade punts again going into the fourth quarter. The Raiders, taking over close to midfield, marched into Eagles territory, but Tavecchio missed a 48-yard field goal to leave the game tied. On the Eagles' next drive, Foles threw an interception and the Raiders drove deep into Philadelphia territory poised to take the lead. However, Jalen Richard turned the ball over on a fumble, the Raiders third turnover of the game. Following punts by both teams, the Raiders took over near midfield with the opportunity to set up a potential game-winning drive. However, with less than a minute to go, Carr threw another pick, the Raiders fourth turnover in the game. Philadelphia used the momentum to close into field goal range, and Elliott connected on a 48-yard try to give the home team the lead with 22 seconds left. Oakland took over on their own 40 with all three timeouts, but moved nowhere. On fourth down, with three seconds left, the Raiders began to lateral the ball as the clock expired attempting to score, but ended up fumbling the ball and the Eagles Derek Barnett returned it for a touchdown. The Eagles took a knee on the extra point try. The Raider defense played well, allowing 216 yards to the Eagles, but the Raider offense lost three fumbles in the game and Carr threw two interceptions. With the loss, the Raiders fell to 6-9 on the season, their third losing season in four years with Derek Carr as QB, and to third place in the division.

Problem: Since its inception, the department has had its temporary headquarters in Washington, D.C.'s Nebraska Avenue Complex, a former naval facility. The 38-acre  site, across from American University, has 32 buildings comprising 566,000 square feet  of administrative space. In early 2007, the Department submitted a $4.1 billion plan to Congress to consolidate its 60-plus Washington-area offices into a single headquarters complex at the St. Elizabeths Hospital campus in Anacostia, Southeast Washington, D.C. The earliest DHS would begin moving to St. Elizabeths is 2012. The move is being championed by District of Columbia officials because of the positive economic impact it will have on historically depressed Anacostia. The move has been criticized by historic preservationists, who claim the revitalization plans will destroy dozens of historic buildings on the campus. Community activists have criticized the plans because the facility will remain walled off and have little interaction with the surrounding area.On January 8, 2009, the National Capital Planning Commission approved the Department of Homeland Security's plans to move into the campus of St. Elizabeths Hospital.In February 2015 the General Services Administration said that the site would open in 2021.

Problem: In July 1449 Esen Tayisi  of the Mongols launched a large-scale, three-pronged invasion of China with his puppet khagan Toqtaq-Buqa. He personally advanced on Datong  in August. The eunuch official Wang Zhen, who dominated the Ming court, encouraged the 22-year-old Zhengtong Emperor to lead his own armies into battle against Esen. The size of Esen's army is unknown but a best guess puts it at some 20,000 men. The Ming army of about 500,000 was hastily assembled; its command was made up of 20 experienced generals and a large entourage of high-ranking civil officials, with Wang Zhen acting as field marshal. On August 3 Esen's army crushed a badly supplied Chinese army at Yanghe, just inside the Great Wall. The same day the Emperor appointed his half-brother Zhu Qiyu as regent. The next day he left Beijing for Juyong Pass. The objective was a short, sharp march west to Datong via the Xuanfu garrison, a campaign into the steppe and then a return to Beijing by a southerly route through Yuzhou. Initially the march was mired by heavy rain. At Juyong Pass the civil officials and generals wanted to halt and send the emperor back to Beijing, but their opinions were overruled by Wang Zhen. On August 16, the army came upon the corpse-strewn battlefield of Yanghe. When it reached Datong on August 18, reports from garrison commanders persuaded Wang Zhen that a campaign into the steppe would be too dangerous. The "expedition" was declared to have reached a victorious conclusion and on August 20 the army set out back toward China proper.
