Religious Affiliation: Episcopalian
"I believe that public tax money for education should be confined to what is basic education and not such auxiliary services as transportation, sports, cultural television and such ancillary Federal programs as Operation Headstart.
"But I believe just as firmly that if we are to continue financing these ancillary services from tax dollars ?and they have grown up around the public school system as extensions of basic education ?then they should be provided equally to all children, those in private and parochial schools as well as those in public schools." -- News Release and Statement on Tax Refunds for Basic Education, October 6, 1967
