As a senator, Nixon received an annual salary of $12,500 (). While he received an expense allowance of over $75,000, more than most senators received (because California was one of the most populous states), that money went to pay his staff of twelve and to cover the cost of stationery, telephone service, telegrams, and other office expenses. It also paid for the one set of round-trip airline tickets between Washington, D.C., and California that Nixon was allowed to buy for himself and his family at taxpayer expense each Congressional session.
