"The White House presented this chair to the owners of the Congress Hotel in the early 1900s," a plaque on the chair reads. "It was a favorite of Presidents Polk, Van Buren, Harrison, and Harding...and it's a favorite of ours too!"
After doing some research, I learned that the hotel's nickname is "Home of Presidents" because Presidents Grover Cleveland, William McKinley, Teddy Roosevelt, William Howard Taft, Woodrow Wilson, Warren Harding, Calvin Coolidge, and Franklin Roosevelt all worked and stayed at the Congress Plaza at some point.
The presidents used the hotel as campaign headquarters, as a meeting place for caucuses, and for historic interviews.
