Funding Homeland Security Dept

Part of the recent budget deal, that funded the Federal government until September, was to stiff arm the Dept of Homeland Security, over Obama's legalizing 4 million illegal immigrants by executive order.  Homeland Security needs to get more funding authorized by the end of February (this month) or shut down.  The idea was to defund Obama's massive amnesty program.  Obama went along with this, and signed the budget deal, probably figuring that Homeland Security would eventually get it's funding, after some political posturing in Congress. 
  Some parts of Homeland Security, the Coast Guard being the shining example, deserve  funding 'cause they do a lot of good.  Other  parts like the Secret Service need heavy duty reform.   Yet other parts, like the Science and Technology Directorate, we could probably do without.  And the Transportation Security Agency ought to be disbanded.  We don't need federally funded goons groping women as they board airliners. 
   And, Homeland Security does the federal flood insurance program, a terrible money sink, that  pays off landowners who build on flood plains.  They get flooded on a regular basis, paid off, they rebuild on the same site, get flooded again, get paid off again.  No commercial insurance companies will touch flood insurance because of the massive and predictable losses.  The government picked it up because of the wailing and crying from the real estate community, realtors, builders, and banks.
  Hopefully, Congress will fund the needed parts of Homeland Security and give the unneeded parts a severe haircut. 

Can he fire anyone?

OK, Obama dumped the head of secret service and appointed a new old guy.  Name escapes me, despite a lotta TV coverage I haven't cuaght his name yet.  Not a good sign.
  Clearly Secret Service has some problems, fence jumpers making to the East Room, agents on trips getting drunk and laid, ex-con with a gun riding the elevator with the president. 
   I'd guess these problems come from ineffective supervisors, officers we called 'em in the military, dunno what the secret service calls 'em.  To fix things, you gotta fire the ineffective supervisors and replace them with good people.  Will the new guy (who is retired secret service and ought to know the people) be able to fire the inefficient?  On his own say-so?  Fairly quickly, like within a few weeks rather than after years of hearings and appeals?  Does secret service have a union to protect the guilty?  Are they under civil service, which basically forbids firing even for very strong cause?
