Former intel officer says 'non-human biologics’ found at alleged UFO crash sites

For additional context, the 14N (Air Force Intelligence officers) community broadly does not support this person or his claims.

Take that for what it's worth

This hearing really isn't about theory or based on your notions of what is likely. Instead, it stemmed from a whistleblower complaint regarding bureaucratic security layers to obfuscate projects from Congressional oversight. These projects are compartmentalized behind SAPs and misappropriation of government funds.

Probably the same amount of evidence the whistleblower has to support theirs.

Presuming there was actually some aliens/UFOs to know about in the first place (I'm pretty confident there aren't any actual alien UFOs, but that doesn't mean there aren't secret programs dedicated to UFOs), it is likely that most of congress wouldn't know about it and only a few congressmen on the right committees would know. Not every member of congress is informed of all the secrets the American government has. Particularly, those 17 on the Senate Select Committee on Intelligence know a lot more than the rest. And even they may be kept in the dark about some things.

The point is program management & constitutionality:

1. Do programs exist over which Congress has no knowledge and/or oversight. If so, this is likely unconstitutional.

2. Do programs exist because Congressionally appropriated funds have been covertly redirected to those programs without Congressional knowledge. If so, likely unconstitutional.

3. Have whistleblowers been threatened or harmed to prevent disclosure and/or testimony. If so, likely a violation of US criminal statutes, and likely unconstitutional - particularly if those whistleblowers intended to provide Congressional testimony in accordance with Congress's oversight role.

The point is not disclosure, confirming existence or declassification - despite what you may hear. It could be one or more of those things occur, but likely not via these hearings.

Oversight can be as simple as notice to the "Gang of Eight" ( https://en.wikipedia.org/wiki/Gang_of_Eight_(intelligence), or possibly the Intel/Defense committee ranking members, and need NOT to be to the entire Congress or even full committee membership. The accusations in these hearings seem to allege this minimal notice did not take place. The testimony also claims extra-governmental (possibly private sector) program management with no political accountability.

In sum... this appears to be a (necessary) power struggle over programs & information. At the same time - and depending on what the real truth may be - one can make a convincing argument little of this information should be public & these programs should remain off the books. Depends on your confidence in the body politic and Congress.
