In short, Trump’s tax immunity deal is unenforceable. Asked by senators whether the immunity remained in effect anyway, Blanche said yes; the ruling, he said, was under “review.” An IRS commissioner who opened an audit of the Trump Organization tomorrow would breach no judgment, statute, or agreement. The only thing standing between the Trump family and an examination is the current management of the IRS. The immunity exists on a single page, signed by a single official, construed to mean whatever the current week requires.
