The controversy spread to both houses of Congress and grew (through the efforts of three of Mondale's fellow committee members, Republicans Margaret Chase Smith, Edward Brooke and Charles H. Percy) to include the second-guessing of NASA's original selection in 1961 of North American as the prime Apollo spacecraft contractor, which Webb became forced to defend. The House NASA oversight committee, which was conducting its own hearings and had picked up on the controversy, was ultimately given a copy of the Phillips report.
