Yesterday, we saw a clip featuring the debut of Sharon Leal's Miss Martian and today, The CW has released a new clip featuring former Wonder Woman actress Lynda Carter as the POTUS. In this scene, the fictional Madame President visits the DEO to discuss her Alien Amnesty Act with J'onn J'onnz. Surprisingly, it would appear that Martian Manhunter doesn't think opening up the Earth to other aliens is a good idea.
