Unclassified scientists and other workers at Yoyodyne JPL (a government lab devoted to space science and operated by CalTech) are now being required to undergo an intrusive government background check process that, among other things, examines their sexual history and orientation. There's no statement that their political leanings are also being examined, but there's also no statement that they aren't.

This quote from the L.A. Times version of the story is especially unreassuring, given the present administration's history of politicizing previously nonpartisan executive-branch units:

David Mould, a NASA spokesman in Washington, said JPL employees were being treated no differently than other executive branch workers.
The Bloomsberg version of the story states that "the requirements are part of a uniform identification system for federal employees", but the New York times clarifies that the affected scientists are not actually federal employees.
