On cordex question, no it doesn't cover video, it's our wiretapping law, so it specifies audio recordings. I suspect that the agent's comments would be the interesting part of this recording though. Unless they went full J. Edgar with Melania's wardrobe.
As far as I know, there isn't any precedent on non consensual recording of cops where an expectation of privacy exist. You explicitly can record them in public, but inside a home while they serve a warrant? Not sure if that case law exists.
