• Winston Churchill flatly refused to sleep in the room that was once known as Lincoln’s sleeping chamber. After having sighted the ghost of Lincoln himself, he insisted upon staying in a different room altogether. Apparently, just after Churchill had left the bathtub and headed for the bedroom – wearing nothing but his cigar – he came face-to-face with Abe, at which time he had the wit to say, “Good evening, Mr. President. You seem to have me at a disadvantage.” At that, Churchill reported, Lincoln simply smiled gently and vanished.

• Although most presidents – who served after the sightings of Lincoln’s ghost were reported – took to the hauntings in a good-natured way, the one exception was former President Richard Nixon, who was known to have ordered the spirit to “Quit messing up my damned recording devices!” Hey, there’s a surprise.

• According to Tobias Johnson – a butler since the days of the Kennedy Administration – Lincoln’s ghost is always quite polite and typically seeks to gain your attention with a light tap on your shoulder or a quiet cough.

Among the many witnesses to the various sightings of President Lincoln – aside from the ones previously noted – were Theodore and Eleanor Roosevelt, Dwight Eisenhower, Harry Truman, Jacqueline Kennedy, Lady Bird Johnson and Maureen Reagan.

Honest Abe wasn’t the only ghost who has been reported to haunt the White House, however. According to a variety of sources, there are a number of others – both presidential and otherwise – who have decided to take up permanent residence there, as well.
