Really outrageous extortion. UCLA and UC as a whole are running budget deficits and facing reduced state support (as well as the grant cancelations). There's simply no money for this and the white house knows it.
That is not relevant to what I am saying at all. I am saying that there is no legal basis for demanding 1 Billion dollars in as that is 1) a made up number from Trump's head, 2) UCLA is innocent until proven guilty, 3) withholding Federal grants duly awarded violates impoundment.
Being broke has never been an excuse to not pay fines.
(I make no judgement on the actual claims, the courts exist for that)
