Carter brokered the Camp David Accords there in September 1978 between Egyptian president Anwar al-Sadat and Israeli prime minister Menachem Begin. Ronald Reagan visited the retreat more than any other president. In 1984, Reagan hosted British prime minister Margaret Thatcher. Reagan restored the nature trails that Nixon paved over so he could horseback ride at Camp David. George H. W. Bush's daughter, Dorothy Bush Koch, was married there in 1992, in the first wedding held at Camp David. Bush Sr. was a golfer. During his tenure as president, Bill Clinton spent every Thanksgiving at Camp David with his family. In July 2000, he hosted the 2000 Camp David Summit negotiations between Israeli prime minister Ehud Barak and Palestinian Authority chairman Yasser Arafat there. In February 2001, George W. Bush held his first meeting with a European leader, British prime minister Tony Blair, at Camp David to discuss missile defense, Iraq, and NATO. During his two terms in office, Bush visited Camp David 149 times, for a total of 487 days, for hosting foreign visitors as well as a personal retreat. He met there with Blair four times. Among the numerous other foreign leaders he hosted at Camp David were Russian president Vladimir Putin and President Musharraf of Pakistan in 2003, Danish prime minister Anders Fogh Rasmussen in June 2006, and British prime minister Gordon Brown in 2007. Barack Obama chose Camp David to host the 38th G8 summit in 2012. President Obama also hosted Russian prime minister Dmitry Medvedev at Camp David, as well as the GCC Summit there in 2015. Donald Trump hosted congressional leaders at Camp David as Republicans prepared to defend both houses of Congress in the 2018 midterm elections. The 46th G7 summit was to be held at Camp David on June 10–12, 2020, but was cancelled due to health concerns during the ongoing COVID-19 pandemic. To be able to play his favorite sport, President Eisenhower had golf course architect Robert Trent Jones design a practice golf facility at Camp David. Around 1954, Jones built one golf hole – a par 3 – with four different tees; Eisenhower added a 250-yard (228.6 m) driving range near the helicopter landing zone. On July 2, 2011, an F-15 intercepted a civilian aircraft approximately from Camp David, when President Obama was in the residence. The two-seater, which was out of radio communication, was escorted to nearby Hagerstown, Maryland, without incident. On July 10, 2011, an F-15 intercepted another small plane near Camp David when Obama was again in the residence; a total of three were intercepted that weekend.
