After failing to keep him off the ballot over issues with his tax returns, California Democrats have now resorted to investigating gubernatorial candidate Larry Elder’s financial disclosures.

According to the Hill, California’s Fair Political Practices Commission (FPPC) has launched an investigation into Larry Elder’s financial disclosure after the state’s Democratic Party “filed a complaint against Elder, accusing the Republican of not properly disclosing aspects of his finances and business.”

Earlier in the month, the Los Angeles Times reported that Larry Elder “improperly listed financial disclosures related to Laurence A. Elder & Associates Inc, a business which experts told the news outlet it appeared he owned.”

In Elder’s Statement of Economic Interests, the Times reported that the candidate did not specify that he owned a stake of the company and only indicated that it was “a source of income”:

An Elder spokeswoman had told the Times that “it appears there might have been an oversight” and his filing was later updated to show that he owned 100 percent of the company. He also updated that the company was valued at between $100,000 and $1 million.

Additionally, the updated filing indicated that Elder had received donations from the Epoch Times and Alachua County (Fla.) Republican Executive Committee, the Times reported.

The FPPC told the lawyer representing California’s Democratic Party that it has not made a determination about the validity of the allegations.

“You will next receive notification from us upon final disposition of the case. However, please be advised that at this time we have not made any determination about the validity of the allegation(s) your client has made or about the culpability, if any, of the person(s) identified in the complaint,” the letter to the lawyer said.

Elder could be charged a maximum of $5,000 for each penalty if found guilty of the violation. Elder’s campaign spokeswoman Ying Ma said in a statement that the investigation is “very common in the campaign world,” arguing that Elder made a simple mistake.
