The senate push for the executive branch's committee of experts is the big one. The house's collection of random interested pol's were never going to get their own select committee, in my opinion. But I think the house leader sees an opportunity to use this to diffuse some other tensions within his party, plus interested constituents on the right are very vocal, (and unfortunately, probably ready to play all kinds of association games with their enemies of the day.)
More hearings, more info, more whistleblowers(???), any forward movement, exploration, investigation, is better than hearing the same old things again. It less becomes about how to convince Congress, and more how to catch these slippery weasels that we trained and equipped to be slippery weasels. How to find the red tape to cut it, how to scare these well hidden groups out of their cells with the idea of consequences, when they may think public authority has no hold over them. Or that they supersede that authority and serve a higher one. (An embedded, underground, rogue government organization is a problem, lol. Basically making them the Enclave from Fallout. )
edit:
the dual messaging that conspiracies don't exist, and the implied message that the public should not assume that lots of things are hidden(more government trust) is always interesting.
it's like government gets on paper that the public has less trust, but they are not unanimous in thinking the response should be to become more trustworthy and transparent. like in this case its literally the politicians vs the soldier-spies, lol. they just need more programs to 'combat disinformation and public paranoia', I guess....
its like while real life political intrigue happens internationally, the commercial media is domestically feeding one side Q-anon and vote steals, with the other side getting constant uh-oh Trump\world falling apart, and both sides feel like something is not right... and we're so off balance we might never figure out what. Individually we're stuck supporting our teams and what they want, assuming that it's also what we want, but wondering why we never seem to get ahead. and it seems like instead of moving forward, society is just pushing the wheel that turns the giant millstone of civilization. Make a little progress, moving forward, and realizing we've all been here before.
Here we are again, back at the issue of weird shit in the sky, and the US Gov trying to decide whether it's something they want to talk about, or avoid again for national security reasons.
