Biography
Vincent Hallinan was a combative San Francisco trial lawyer who defended longshore leader Harry Bridges in his 1949–50 denaturalization and perjury trial. For his aggressive courtroom defense, Judge George Harris jailed him for contempt of court; the Supreme Court declined to review, and Hallinan served six months — after which he ran for President in 1952 on the Progressive Party ticket.
National Guardian, October 19, 1953, national page 16: Vincent and Vivian Hallinan were on trial in San Francisco before federal Judge Edward P. Murphy on allegations of evading about $65,000 in income taxes for 1946–1950. The paper says they were indicted the previous March and quotes Vincent's claim of political retaliation and denial that any tax was owed. It separately recalls his six-month contempt sentence from the Harry Bridges defense. The tax trial was ongoing: no guilty verdict, sentence or actual tax-case custody is established by this issue. A captioned portrait identifies Vincent Hallinan; the existing production portrait was preserved. Source: https://www.marxists.org/history/usa/pubs/national-guardian/1953-10-19-5-52-nat-guardian.pdf
The National Guardian reported that Vincent Hallinan entered McNeil Island Penitentiary in Puget Sound, Washington, on April 1, 1952 to begin serving a contempt sentence arising from his defense of Harry Bridges. This supplies a named institution for the already recorded April 1 admission; the nominal six-month sentence does not replace the existing documented 138-day served total or later physical-release date.
