Billings spent less time with the President in the fall of 1963. One of their friends thought "that Jackie was trying to close Lem out." Billings spent the last weekend of October 1963 with the couple, the last time he saw them together. Billings saw the President for the last time when they dined at the White House with Greta Garbo on November 13, 1963, nine days before the President's assassination in Dallas.
