On March 13, Willis petitioned the Senate for a review of the election, alleging tampering with tabulation machines and allowing improperly registered persons to vote. Willis also charged that recipients of Works Progress Administration jobs and relief were pressured to vote for the Democrats, and he complained about the infamous Two Per Cent Club, which was said to have violated the corrupt practices acts by collecting and disbursing thousands of dollars for the senatorial election without keeping appropriate records. He made no allegation that Van Nuys was involved or aware of corrupt practices.
After one month's investigation, the Senate Committee on Privileges and Elections returned a report favorable to Van Nuys, and it was carried by a voice vote of the whole Senate.
