The May 12, 2016, House witness biography states that Neffenger became the 29th Vice Commandant of the United States Coast Guard in May 2014. Harvard NPLI and CNA later bios use the same ordinal. The Senate roll-call page for his 2015 nomination lists him as Peter V. Neffenger, of Ohio, to be an Assistant Secretary of Homeland Security — the statutory title that accompanies the TSA Administrator job.
DVIDS still hosts a Coast Guard photograph of Vice Adm. Neffenger at Headquarters on August 4, 2014, Coast Guard Day. That image is a U.S. government work. It is identity, not commentary.
This site does not invent a 2026 active-duty rank. He is a retired vice admiral in later bios.
