Nixon came from a family of modest means, as he related in the address, and he had spent his time after law school in the military, campaigning for office, and serving in Congress. After his successful 1950 Senate campaign, his backers continued to raise money to finance his political activities. These contributions went to reimburse him for travel costs, postage for political mailings which he did not have franked, and similar expenses. Such a fund was not illegal at the time, but Nixon had made a point of attacking government corruption which exposed him to charges that he might be giving special favors to the contributors.
