William Daniel Johnson (born 1954) is a White Nationalist, a longtime American attorney, and the chairman of the American Freedom Party.
Johnson graduated from Brigham Young University where he majored in Japanese and later served as a Mormon missionary in Japan.
Before becoming an activist, Johnson's background was as an attorney. He was admitted to the bar in California in 1981, Colorado in 1990, and Arizona in 2006.
In the 1980s, Johnson began to use three separate identities to promote his work. Under the name James O. Pace, he wrote a 1985 book advocating a constitutional amendment (the "Pace Amendment") that would repeal the 14th and 15th amendments and deport almost all non-whites from the United States. This proposal was similar to one advocated earlier by J. B. Stoner. The Pace Amendment proposed defining whiteness thusly:
No person shall be a citizen of the United States unless he is a non-Hispanic white of the European race, in whom there is no ascertainable trace of Negro blood, nor more than one-eighth Mongolian, Asian, Asia Minor, Middle Eastern, Semitic, Near Eastern, American Indian, Malay or other non-European or non-white blood, provided that Hispanic whites, defined as anyone with an Hispanic ancestor, may be citizens if, in addition to meeting the aforesaid ascertainable trace and percentage tests, they are in appearance indistinguishable from Americans whose ancestral home is in the British Isles or Northwestern Europe. Only citizens shall have the right and privilege to reside permanently in the United States.
Under the Pace amendment, indigenous Americans and Hawaiians would be maintained in tribal reservations instead of being deported. The Pace book included dust-cover comments written by Richard Girnt Butler and Dan Gayman. In 1986, he promoted the book by attending Butler's Aryan Nations World Congress.
Under the name "Daniel Johnson", Johnson founded the League of Pace Amendment Advocates, a group dedicated to promoting the Pace amendment. In his capacity as an attorney, Johnson used the name "William D. Johnson". In 1987, following an expose by the Los Angeles Times, it quickly became clear that "Pace" and both Johnsons were all the same person. This came to light partly because the League had been infiltrated by a member of the Simon Wiesenthal Center, which opposed the amendment.
