What type of research are you wanting, exactly?
Here's what I can tell you. This whistle-blower is either not keeping up with the news, or this is recycled old news (yeah, shocking, I know).
This has already been made public. Months ago. You can read all about what happened here:
To sum it up: USPS briefly tried to restrict contractors’ use of certain non-domiciled CDL drivers earlier this year. It was a USPS contracting policy, not a DOT or FMCSA rule, and it failed fast because it disrupted mail delivery. USPS walked it back. That’s all documented and public.
There is no nationwide DOT or FMCSA ban on non-domiciled CDLs in effect, no executive order quietly doing this, and no secret January 1, 2026 cutoff hiding in the shadows. If that existed, it would be in the Federal Register, in court dockets, and all over industry compliance bulletins. It isn’t.

Also, USPS doesn't control CDLs. The FMCSA sets the national rules and minimum standards for CDLs. States issue the licenses through their DMVs, run the tests, and manage the drivers day-to-day. FMCSA’s role is oversight and enforcement — auditing states, enforcing compliance, and stepping in when a state fails to meet federal safety requirements.
Why anyone would think the United States Postal Service has the authority to issue or revoke Commercial Drivers Licenses or has any oversight at all in regards to them is absolutely beyond me.
