I mean by definition they all are deep state. They've all been in government for ages and what do they do for us.

You should also look into the bureaucracy and how Obama changed, packed, and weaponized it with his EOs and other tactics like using the IRS to audit political opponents. This is also what is meant by "the deep state." Look into it but long story short Obama ruled through many EOs that can't be enforced normally, so he had to create agencies and bureaus to enforce them, this created a big bloated government with people who are all loyal to Obama.
