Read the whole article. It's not about impeachment. The relevant portions of the statute are detailed there. If Obama violates any portion of that law (which he probably will), he most certainly can be prosecuted and removed from office.
The only question is, who's going to have to cojones to do it? The author (Dr. Jack Wheeler) suggests that several red state Governors could band together and bring suit, as provided for in the law.
I'm going to send this to my Governor, Rick Perry, my House rep, Kenny Marchant (R-TX), and both of my Senators, one of which is Ted Cruz (R-TX).
“he most certainly can be prosecuted and removed from office”
No, he MUST be impeached first. Breaking this law may be grounds for impeachment, but you are talking as if immediate prosecution can replace impeachment. It can’t.
“several red state Governors could band together and bring suit”
They could, but they can’t remove him from office. Only Congress can: the house through impeachment and the senate by trial and conviction.
