I don't think the White House denied that Elon Musk was under investigation. It would be...completely inappropriate for the White House to comment on specific investigations from the FBI or DOJ.
Rather, the White House denied that there was a national security review of Elon Musk's projects. That's important, but very distinct from a denial that there are no investigations of Elon Musk. It's also a subject matter that is much more appropriate for the White House to comment on.
That statement is about a national security review. What Reuters report do you think this disputes? Reuters reported on an investigation claim made by others in court:
"There's a lot of interest in this. We heard those reportings, those reportings are not true, so we'll leave that there. The national security review, that is not true and I really don't have more to say on that piece, on Elon Musk and what he's choosing to do and not to do, I'm not going to say more from here".
Which... sounds exactly like what the person you are replying to was saying.
