However, given that the British used those sources and methods to help our own intelligence people more or less plant false evidence to get Mueller appointed, we should not worry about what they think. Those people are not Trump’s friends, and he owes them nothing.
In my view, Trump needs to tell Mueller to put his cards on the table, and do it now, or he will again order that everything be declassified. It has been two years. Mueller needs to stop this shit show. Whatever integrity he may once have, whoever he may once have been, he is no more. He has become a Javert obsessed with Trump, and willing to break any vow, any code, and any law to do it.
And Javert, in the end, did the right thing. There is no sign that spirit has any residence any more in this craven and awful man.
