In 1947, after the US Supreme Court's finding (in "Morgan v. Commonwealth") that segregation in interstate travel was unconstitutional, Houser helped organize the Journey of Reconciliation. This was a plan to send eight white and eight black men on a journey through Virginia, North Carolina, Tennessee, and Kentucky to test the ruling. The protest brought a great deal of press attention to CORE and to the issue of segregation in interstate travel. In February 1948 George Houser received the Thomas Jefferson Award for his work to bring an end to segregation on interstate buses and in their facilities.
