TSA is in DHS, DHS does not dictate ATC policy.
No the POTUS does and he probably listens to DHS more than DOT.


What ATC policies have been dictated by the POTUS? Why would the POTUS rely
on DHS for ATC policy over DOT? Would he rely on DOT over DHS on security
matters?



And policy promulgated by DOT, DHS, DOD, is dictated by the POTUS. In
most cases it is actually dictated by people he selects to handle those
departments but the final authority rests on the desk of the POTUS.

As for your other two questions think overlap.
