NCIS Season 11
Following the death of current SECNAV Clayton Jarvis in an explosion at a hotel which occurred during the Season 11 premiere episode, Whiskey Tango Foxtrot (episode), Porter was sworn in as Jarvis's replacement and made her debut appearance in the Season 11 episode, Past, Present and Future (episode) where she met NCIS Special Agent Leroy Jethro Gibbs and FBI Special Agent Tobias Fornell with NCIS Director Leon Vance making the introductions.
Porter remarked that being appointed as "bittersweet" and that Jarvis had been a friend of hers. She then repeatedly visited the NCIS Headquarters to check progress on the hunt for the terrorist group, the Brotherhood of Doubt and its leader, Benham Parsa.
Porter's next appearance came in Oil and Water (episode) where she made a visit to NCIS HQ.
Porter returned in Gut Check (episode) where she later ended up becoming an unwitting accomplice in a security breach when it became apparent that a pen she had in her possession had been bugged during a briefing.
This, alongside a prior NSA report made by then-NSA analyst Eleanor Bishop that had predicted this security breach, resulted in the NSA (Bishop, more specifically) teaming up with the NCIS Major Case Response Team led by NCIS Special Agent Leroy Jethro Gibbs to investigate the people responsible for the security breach.
It was also revealed during the case that Porter had an unnamed teenage daughter.
