I'll start...just off the top of my head:
The Federal Reserve and its goon squad, IRS
FBI
16 other "intelligence" agencies - which one can stay?
EPA
FDA
FEMA
NPR
ATF
DEA
OSHA
DOE - send education back to the states
DOT - transportation just happens; no govt teat-suckers needed
Dept of Commerce - commerce just happens; no govt teat-suckers needed
DHS - we already have a DEFENSE department to secure our homeland
DHHS - govt is unqualified to have any input about your health: they want you sick, dying, and in fear of sickness and dying, for maximum CONTROL over your life
Dept of the Interior - what, like without this we'd have only an exterior?
NEA - National Endowment for the Arts - People who value art and want to buy it should support artists by buying art - taxpayers should not be bent over and have tax dollars extracted from their colon for some misfit with matted hair and gingivitis to piss on a crucifix, tape a banana to it, and call it art
