trump was president. It was him that forced the IRS to outsource to Booz. Then it was Littlejohn, an employ at Booz that leaked it. Had trump not been president, the IRS would not have outsourced it to Booz, and trump could have kept his Russian bribes a secret.
And it will not be the IRS or trump that will pay. It will be the American taxpayers, so me and maybe even you a little.
Booz, which trump forced the IRS to hire, is not a law firm. They are tech consultants who work especially with logistics. It never made sense for the IRS to be forced to hire them.
trump is the guy on both sides of the argument who will decide whether it is absurd or not.
This is just making excuses for the leak. You are just making a post hoc ergo prompter hoc fallacy. That is, you are saying because Trump did X, Y happened. In this case, that's an absurdity.
An employee of Booz decided to front Trump off by releasing his tax returns (along with those of many other rich people). It could just as easily have been an IRS employee, a temp help employee, etc. There is zero correlation between any action Trump took and the fact that a rogue employee with access to those records took it upon himself to release them.
You offer a variant of the Fallacy of exclusive premises here. To wit:
All IRS employees are trustworthy and would not release this data.
Trump forced the hire of Booz whose employees are not IRS employees.
Therefore, because Trump forced the hire of Booz, a leak of data occurred.
This is obviously bullshit. An IRS employee could easily be just as corrupt and willing to do this breech. If the IRS needed outside tech support, they could have hired any number of companies besides Booz. That an employee at Booz was corrupt and willing to do this breech, is entirely one of chance, not prior planning or knowledge. Therefore, Trump did not have anything to do with this situation.
Trump, like anyone else affected by this leak, has the right to sue to the government for it if they feel they were harmed by it. The figure asked for is irrelevant as the court(s) will decide in the end what, if any, monetary penalty will be.
