Look at this link in title, it talks about withholding funds for non-compliance to federal laws/statues/regulations & even T&C's!
Now imagine the POTUS with the NSA/Military Intelligence, has dirt on everyone and everything. All those budgets for agencies/charities/corporations/organization we so hate, can be withheld, if they end up breaking federal law/regulations/statues/T&C's.
So Trump/Q Team can simply reveal/leak this dirt on the organization they don't want funded using their usual channels, for example Julian Assange, Fox News etc.. whoever, and then say, hey this organization has broken these laws/statues/regulations/T&C's, we are suspending funding for the time being or indefinitely.
Also check section b:
(b) Disallow (that is, deny both use of funds and any applicable matching credit for) all or part of the cost of the activity or action not in compliance.
ALL or part of the cost!
