Let’s distinguish a bit. There are political appointees (Trump’s government employees as you say) who are mostly upper management, and there are career civil servants (all the government scientists are under this category) who have a strong culture of apolitical dedication to the mission of their agency and to the American people and Constitution, regardless of who the current president is. And in the DOE labs in particular most (not all) of the scientists are actually employed as government contractors, but they have a similar non-partisan ethos.

That doesn’t necessarily mean there’s no need to be concerned with potential impact of policy and priority changes from the administration, but it does temper the threat model because the government employees you’re considering trusting have given oaths of office to protect and defend the Constitution.
