Models Kate Upton and Miranda Vee have accused Marciano of sexually and emotionally harassing them while they were working for the company.
Upton had alleged Marciano grabbed her breasts during a meeting and retaliated against her when she refused his advances.
Vee claims Marciano harassed her at the Guess headquarters and introduced her to Mohamed Hadid, who she alleges sexually assaulted her. Vee has filed a police report with the LAPD alleging sexual assault against both men.
Earlier this month, Guess formed a committee to investigate the allegations of improper conduct against Marciano.
“I have pledged my full cooperation to the company,” Marciano said in a press release Tuesday. “And I have the utmost confidence in our CEO, Victor Herrero, to continue leading the Company during this time.”
