Senior DOJ prosecutor quit after being told to investigate Biden climate spending

She did. Per the article:

While Bove’s office insisted that it had, citing a Project Veritas video, Cheung and others didn’t believe the evidence on hand was enough for a grand jury investigation, her letter and additional sources told CNN.

She said after the pushback, the Justice Department instead wanted to freeze assets in a bank related to the Biden-era EPA funding.

Project Veritas content is seriously compromised much of the time; it's often undercover video which is selectively edited to produce something misleading. You can't use it as evidence without getting the rest of the context.

The problem is that when you have a direct order to commit a crime, the choice is:

• resign
• be fired and escorted out a few minutes later
• do the crime

Being fired is a few minutes later isn't preferable to resigning, though a few people have.

Stick around and sabotage is something you can do when you're not directly ordered to do something criminal.

Doing your job poorly is CIA endorsed antifascist praxis

That's pretty much every conservative employee during a Democrat's run at office.

Resigning is stupid and what they want so they can replace them faster.

Do you mean as in civil dissobedience (so that the administration are forced to fire you or accept that you aren't going along with facism) or as in sneak ops sucking at your job to slow things down?

I like both ideas! I'm sure plenty do them as well, but maybe get less attention/coverage than high prifile resignations.

Some people who have dignity for themselves, would rather serve their position honorably and be mistaken because they're human. They don't want to do their job poorly that directly violates their own work ethic and the duty they have sworn to uphold.

Resigning in this case is basically saying "I will not be told how to do my job because you don't understand how it works and I will not let you use my job as a means to play political theater".
