Problem: Richard Milhous Nixon was born on January 9, 1913 in Yorba Linda, California, in a house that was built by his father. His parents were Hannah (Milhous) Nixon and Francis A. Nixon. His mother was a Quaker, and his father converted from Methodism to the Quaker faith. Nixon was a descendant of the early American settler, Thomas Cornell, who was also an ancestor of Ezra Cornell, the founder of Cornell University, as well as of Jimmy Carter and Bill Gates.

Nixon used the improving international environment to address the topic of nuclear peace. Following the announcement of his visit to China, the Nixon administration concluded negotiations for him to visit the Soviet Union. The President and First Lady arrived in Moscow on May 22, 1972 and met with Leonid Brezhnev, the General Secretary of the Communist Party; Alexei Kosygin, the Chairman of the Council of Ministers; and Nikolai Podgorny, the head of state, among other leading Soviet officials. Nixon engaged in intense negotiations with Brezhnev. Out of the summit came agreements for increased trade and two landmark arms control treaties: SALT I, the first comprehensive limitation pact signed by the two superpowers, and the Anti-Ballistic Missile Treaty, which banned the development of systems designed to intercept incoming missiles. Nixon and Brezhnev proclaimed a new era of "peaceful coexistence". A banquet was held that evening at the Kremlin. Seeking to foster better relations with the United States, both China and the Soviet Union cut back on their diplomatic support for North Vietnam and advised Hanoi to come to terms militarily. Nixon later described his strategy: I had long believed that an indispensable element of any successful peace initiative in Vietnam was to enlist, if possible, the help of the Soviets and the Chinese. Though rapprochement with China and detente with the Soviet Union were ends in themselves, I also considered them possible means to hasten the end of the war. At worst, Hanoi was bound to feel less confident if Washington was dealing with Moscow and Beijing. At best, if the two major Communist powers decided that they had bigger fish to fry, Hanoi would be pressured into negotiating a settlement we could accept. Having made considerable progress over the previous two years in U.S.-Soviet relations, Nixon embarked on a second trip to the Soviet Union in 1974. He arrived in Moscow on June 27 to a welcome ceremony, cheering crowds, and a state dinner at the Grand Kremlin Palace that evening. Nixon and Brezhnev met in Yalta, where they discussed a proposed mutual defense pact, detente, and MIRVs. While he considered proposing a comprehensive test-ban treaty, Nixon felt he would not have time as president to complete it. There were no significant breakthroughs in these negotiations.

Who did they deal with while they were there?

Answer with quotes: met with Leonid Brezhnev, the General Secretary of the Communist Party; Alexei Kosygin, the Chairman of the Council of Ministers;

Question:
Panic! at the Disco is an American rock band from Las Vegas, Nevada, formed in 2004 and featuring the current lineup of vocalist Brendon Urie, accompanied on tour by guitarist Kenneth Harris, drummer Dan Pawlovich, and bassist Nicole Row. Founded by childhood friends Ryan Ross, Spencer Smith, Brent Wilson and Urie, Panic! at the Disco recorded its first demos while its members were in high school. Shortly after, the band recorded and released its debut studio album, A Fever You Can't Sweat Out (2005).
After the Vices & Virtues tour cycle, Urie, Smith, and Weekes began writing and preparing for a fourth album. During the recording of the album, touring guitarist Ian Crawford, who joined the band in 2009 after the departure of Ryan Ross and Jon Walker, left the band citing his desire to make "real, genuine" music. On July 15, 2013, the album was announced as Too Weird to Live, Too Rare to Die!, with a scheduled release date of October 8, 2013. The first single, "Miss Jackson", was released on July 15, 2013, along with its music video to promote the album. Panic! at the Disco opened for Fall Out Boy on the Save Rock And Roll Arena Tour with Kenneth Harris replacing Crawford. Shortly before the band began its first tour in support of the album, Smith wrote an open letter to fans regarding his abuse of alcohol and prescription medications since the recording of Pretty. Odd. Although Smith joined the band for the first handful of dates, he left the tour to "continue fighting addiction". Urie posted on the band's official website on August 7, 2013, that "It's become evident that Spencer still needs more time to take care of himself. I can't expect him to be fighting addiction one minute and be fully immersed in a national tour the next. With that said, the tour will continue without Spencer while he is away getting the help he needs." Since Spencer's leave of absence, Dan Pawlovich of the band Valencia has filled in on tour. In an interview with Pure Fresh on September 23, 2014, Urie stated that he had already thought about ideas on the fifth studio album; however, he was not sure if it would be a Panic! at the Disco album, or a solo album. Urie has also stated there are no current plans for Smith to return to the band.
