How is it partisan?

“ Tesla lawyers and board members scrutinized the project after employees became concerned about how the company planned to use millions of dollars in specialized glass that it had ordered.”

And

“ SEC rules require public companies to disclose transactions above $120,000 in which a related party, such as an executive officer, has a material interest.”

If it’s really a matter of spending corporate money on a personal benefit project, then it must be declared and agreed upon by board and or shareholders. Otherwise it is misappropriation.

I’m no lawyer, so my terms may be inaccurate; but that’s the gist of why this is probably worthy of investigation.
