"Can Obama just cut anything he wants?".
Yes/No. For instance. Say a bill dictating cuts in some program(s) from the HR is passed onto the Senate, approved there, then is sent to the executive branch for signing into law.
He can veto the bill. It then would go back to the Congress for modification or just end up in the trash barrel. So in that respect the answer is a yes.
However. Say the same bill sponsored by both houses come to his desk and he signs it. Then he cannot come back later and say he wants something cut out of it. So in that sense the answer would be an obvious no.
To what extent the use of executive orders can be used to cut funding for a bill that was then signed into law by him, I am not sure of the answer.

You misunderstood my question. I understand vetos and specific agency funding decisions.

My question was “What specifically get’s cut when the debt ceiling is not raised yet the spending budget is $3T move than revenue?”. I bet there is no specific law that mandates that.
