You'll need to plan for two situations: Remaining in your home after a disaster or evacuating to a safer location. Have a three-day supply of food and water on hand -- plan for one gallon of water per person per day and food that won't spoil.
Answer: The only president to ever serve on the Supreme Court was William Howard Taft. President Warren G. Harding appointed him to be Chief Justice in 1921. He served in that position until he retired in 1930. As Chief Justice, Taft was able to make changes giving the court more control over its docket. He also argued for the construction of a separate building for the Supreme Court.
It was quietly administered in the White House by Justice Hoehling of the District of Columbia. The following year Coolidge was re-elected President and prepared to take the oath of office for his second term in a public ceremony, and deliver his first Inaugural Address. It was destined to be an historic celebration. Before his death in 1923, President Harding had appointed a new Supreme Court Chief Justice.
