I’d do more than that

Disband DHS. This agency was never required and was created merely as a knee-jerk to the information sharing problems that contributed to how 9/11 turned out.

Ironically, the majority of those problems were actually between the FBI and CIA and DHS has no authority over either — that role was handled to the also-newly-created Director of National Intelligence (DNI)

Sooooo we never needed the orwellian DHS in the first place

Abolish ICE, HSI and CBP*. The the other constituent agencies carry on as they did before 9/11 and leave the LE/intelligence coordination to the DNI

*Some folks would love to see ATF go, others want the end of TSA
