They just did it to the IRS.
Yes, the House did, but only for ‘enforcement’.
Now the Senate has to go along and it has to survive a Presidential veto. Good luck.
I did hear something about the Senate having input on said purse, because I was surprised to learn it, but the point you made on the HOR passing a partial cut to the IRS is a good one.
I’m confused about what the defunding abilities really are as to and where they apply.
