As tensions grew between the suffragists and President Wilson, he realized something had to be done quickly to end the highly publicized protests and clashes between the police and suffragists. He requested that Congress convene for a special session in May 1919. On May 21 the House of Representatives passed the Susan B. Anthony amendment 304 to 89, and on June 4, the Senate passed it 66 to 30. Surprisingly, the suffragists were very subdued at the announcement of this victory. The suffragists battle was not yet over; they still had to make sure a majority of the states ratified the amendment. Finally, on August 18, 1920, Tennessee became the thirty-sixth state to ratify the Anthony amendment, and Burns' quest for federal suffrage was finally over.
