Senator Tom Cotton

“ First, under our Constitution, while the president negotiates international agreements, Congress plays the significant role of ratifying them. In the case of a treaty, the Senate must ratify it by a two-thirds vote. A so-called congressional-executive agreement requires a majority vote in both the House and the Senate (which, because of procedural rules, effectively means a three-fifths vote in the Senate) . Anything not approved by Congress is a mere executive agreement. ”

“ It has come to our attention while observing your nuclear negotiations with our government that you may not fully understand our constitutional system. 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. ”
