In 1951, Gabrielson became embroiled in a loan scandal, and freshman Senator Richard Nixon (R-Calif.) called for his ouster, as well as that of Democratic National Committee chairman William M. Boyle, a close ally of President Harry S. Truman, who had a similar loan involvement. Nixon feared Gabrielson would favor California's senior senator, William F. Knowland for any national office, and desired his ouster to clear his own path to higher office. Boyle resigned, Gabrielson, whose offense was much more that of appearance, did not resign. Because of the enmity between Gabrielson and Nixon, the senator's name was never entered for formal consideration as a keynote speaker at the convention. Gabrielson would also be one of the few Republican politicians not to offer him support after Nixon, by then the Republican Vice-presidential candidate, placed his fate in the hands of the RNC in the Checkers speech, saying that Nixon's speech (which he had not heard) did not "make sense" because it would take ten days to assemble the RNC.
