Definers Public Affairs, a policy and opposition research firm, has filed an anti-SLAPP (Strategic Lawsuit Against Public Participation) response to a lawsuit from Silicon Valley investor Shervin Pishevar, who accused the firm of coordinating a smear campaign against him. The firm is also asking the court to dimiss the lawsuit, calling the claims "delusional and entirely without merit."

Backstory: Last month, Pishevar filed a lawsuit against the firm after several media outlets, including Axios, inquired about his arrest earlier this year in London for alleged rape. He was ultimately not charged and a court granted his request to keep his name out of the papers. In his complaint, Pishevar accused Definers of spreading rumors about the incident, as well as other information in an attempt to smear him.

• Pishevar invoked his lawsuit and alleged smear campaign in a lengthy statement earlier this week about taking a leave of absence from his VC firm and role at Virgin Hyperloop One. A few days ealier, Bloomberg had published several accounts of women accusing him of sexual harassment and assault.
