San Francisco mayoral candidate Mark Farrell is facing allegations of financial misconduct and money laundering from his opponents. Wealthy donors have contributed significant amounts to a ballot measure committee controlled by Farrell, which is sharing expenses with his mayoral campaign. This practice, involving over $160,000 in pooled expenses, has led to accusations of skirting campaign finance limits. Additionally, Farrell's campaign is under scrutiny for a $50,000 payment to interns, further fueling claims of financial impropriety.
