Disclaimer: This comment is not intended to be political - I don't care about the specific party she's part of.
Out of all the people I would trust on the matter, Kamala Harris doesn't certainly end up at the top of my list, for reasons such as this one: https://youtu.be/O2SLyBL2kdM?si=Zq-EN8zxj4Y_UCwI
You also don't need to be in classified meetings to understand that Bluetooth/ BLE (and specifically the way most vendors implement the spec) is not as secure as other more battle-tested technologies
What she says isn't necessary untrue, now is it? She just skips a lot of steps most people have no clue about.
I had files in a cabinet, now they are digital. And most often also on a cloud drive, which is metaphysical in some sense. For most it is indistinguishable from magic.

There hasn't been a POTUS or VPOTUS with a technical background in the last 45 years (Jimmy Carter was a nuclear engineer). So obviously none of them would be authoritative on such topics.
However the individual in question is not delusional or conspiratorial, and we know for sure that they are receiving advice or restrictions from extremely well-informed sources, so there's every reason to believe they are (lo-fi) repeating that.
It's essentially a statement about the view of gov security, not about the view of an individual.
I think many people would be justified in making the argument that bluetooth has existed for at least 20 years and thus is the established battle tested protocol.
