Stroud died on November 21, 1963.
- Congressman William Willett, Jr. (D-N.Y.) denounced outgoing President Theodore Roosevelt, in terms so outrageous that the House voted 126–78 to terminate his speech. The Washington Post described the speech as "so bitter and sensational that it seemed as though its author had raked the dictionary for adjectives to vilify the chief executive". By the time that he said "the Gargoyle is about to grin its last grin", he was being ruled out of order, and he skipped to the end to say "the Nero who fiddled while Rome was burning will be out of power on March 4th." By voice vote on January 27, the House expunged the speech from the Congressional Record for "language improper".

The Bulletin story, and an accompanying sketch, were soon picked up by papers across the nation. The Washington Post described the creature as having "a head like a collie dog, and a face like a horse... a long neck, wings about 8 feet long, and it whines at intervals. Its tail is described by one Jerseyman as 'glowing like a coal of fire'. The Post commented that "Chills are running up and down the South Jersey spine like a monkey on a stick". The mysterious creature became a fixture of the state's folklore, and is now the mascot for Newark's National Hockey League team.
- After a personal appeal from President Roosevelt, California Governor James Gillett met with state legislative leaders to stop further progress on anti-Japanese legislation.

A bill proposed to limit Japanese-American residents of San Francisco to residing in its Chinatown district, to bar their children from attending public schools, and to bar them from serving as directors of a corporation.

His insight, recorded in a daily journal, was that "if an explosive... is burned in tubes in such a way that all its energy is converted into kinetic energy of the particles expelled and the body propelled, it is, theoretically, possible to obtain propulsion". Goddard's discovery paved the way for space exploration.
