Cole Killian

Wrecker , coder, age 24

Gautier “Cole” Killian was identified early as one of the initial DOGE employees, and there are reports of him interviewing USDS staff about their roles as early as January 21st. He was also spotted in a few of the early wrecking crew raids, but he has largely fallen off the radar since the end of February, when he was detailed to the Social Security Administration. Perhaps he is one of the still-unidentified aliases there and more details of his involvement will become apparent in future court filings and FOIA releases.

Likely aliases: SSA-05
