Now, the GOP is trying to do an end-run around Iran negotiations with this kind of bullshit:

GOP senators send warning on Iran deal

“It has come to our attention while observing your nuclear negotiations with our government that you may not fully understand our constitutional system,” the senators wrote in the letter, which was first reported by Bloomberg. “Thus, we are writing to bring to your attention two features of our Constitution — the power to make binding international agreements and the different character of federal offices — which you should seriously consider as negotiations progress.”

“Anything not approved by Congress is a mere executive agreement,” they said.

“The letter was spearheaded by Sen. Tom Cotton (R-Ark.) and signed by Majority Leader Mitch McConnell (R-Ky.). It was also signed by four Republicans who are said to be considering a run for president: Sen. Marco Rubio (Fla.), Sen. Rand Paul (Ky.), Sen. Ted Cruz (Texas) and Sen. Lindsey Graham (S.C.).”

So, some upstart Tea Party back bencher is the point man for this kind of bullshit, and it’s endorsed by 4 people who will never be president and approved by McConnell?

Cheeez. Talk about interference in foreign policy. First, Netanyahu and now this?
