Question: How many Smithsonian museums are there in the city where the U.S. president who owned a dog named Checkers worked?

full_context: Document 1: Dwight D. Eisenhower: In the 1960 election to choose his successor, Eisenhower endorsed his own Vice President, Republican Richard Nixon against Democrat John F. Kennedy. He told friends, "I will do almost anything to avoid turning my chair and country over to Kennedy." He actively campaigned for Nixon in the final days, although he may have done Nixon some harm. When asked by reporters at the end of a televised press conference to list one of Nixon's policy ideas he had adopted, Eisenhower joked, "If you give me a week, I might think of one. I don't remember." Kennedy's campaign used the quote in one of its campaign commercials. Nixon narrowly lost to Kennedy. Eisenhower, who was the oldest president in history at that time (then 70), was succeeded by the youngest elected president, as Kennedy was 43.
Document 2: Dwight D. Eisenhower: President Truman, symbolizing a broad-based desire for an Eisenhower candidacy for president, again in 1951 pressed him to run for the office as a Democrat. It was at this time that Eisenhower voiced his disagreements with the Democratic party and declared himself and his family to be Republicans. A "Draft Eisenhower" movement in the Republican Party persuaded him to declare his candidacy in the 1952 presidential election to counter the candidacy of non-interventionist Senator Robert A. Taft. The effort was a long struggle; Eisenhower had to be convinced that political circumstances had created a genuine duty for him to offer himself as a candidate, and that there was a mandate from the populace for him to be their President. Henry Cabot Lodge, who served as his campaign manager, and others succeeded in convincing him, and in June 1952 he resigned his command at NATO to campaign full-time. Eisenhower defeated Taft for the nomination, having won critical delegate votes from Texas. Eisenhower's campaign was noted for the simple but effective slogan, "I Like Ike". It was essential to his success that Eisenhower express opposition to Roosevelt's policy at Yalta and against Truman's policies in Korea and China—matters in which he had once participated. In defeating Taft for the nomination, it became necessary for Eisenhower to appease the right wing Old Guard of the Republican Party; his selection of Richard M. Nixon as the Vice-President on the ticket was designed in part for that purpose. Nixon also provided a strong anti-communist presence as well as some youth to counter Ike's more advanced age.

The gift was a black - and - white cocker spaniel, Checkers, given to his daughters.

Document 7: Federal Bureau of Investigation: Beginning in the 1940s and continuing into the 1970s, the bureau investigated cases of espionage against the United States and its allies. Eight Nazi agents who had planned sabotage operations against American targets were arrested, and six were executed (Ex parte Quirin) under their sentences. Also during this time, a joint US/UK code-breaking effort (the Venona project)—with which the FBI was heavily involved—broke Soviet diplomatic and intelligence communications codes, allowing the US and British governments to read Soviet communications. This effort confirmed the existence of Americans working in the United States for Soviet intelligence. Hoover was administering this project but failed to notify the Central Intelligence Agency (CIA) until 1952. Another notable case is the arrest of Soviet spy Rudolf Abel in 1957. The discovery of Soviet spies operating in the US allowed Hoover to pursue his longstanding obsession with the threat he perceived from the American Left, ranging from Communist Party of the United States of America (CPUSA) union organizers to American liberals.
