Final answer:
President Gerald Ford built an outdoor pool at the White House in 1975 following the transition of the indoor pool into the Press Briefing Room.
Step-by-step explanation:
President Gerald Ford built an outdoor pool at the White House in 1975 after the indoor swimming pool was covered over to make space for the Press Briefing Room. Ford's time as president was overshadowed by the aftermath of the Watergate scandal, which had led to the resignation of his predecessor, President Richard Nixon. Despite efforts to address the issues of the time, Ford struggled to overcome the nation's economic problems and the lasting impact of Watergate. This outdoor pool served as a new recreational space, while the historical significance of the indoor pool was preserved.
