I'm Jeffrey Rosen, President and CEO of the National Constitution Center, and welcome to the latest of our We the People constitutional

Podcasts. The National Constitution Center is the only institution in America chartered by Congress to disseminate information

about the U.S. Constitution on a nonpartisan basis.

And this week we confront two hotly contested questions who should control American foreign policy, the president or Congress,

and what does the Constitution say about that balance?

The United States in cooperation with five other major world powers is scrambling to meet a deadline in its ongoing

negotiations with Iran. All parties insist that a preliminary framework for a

nuclear deal has to be in place by the beginning of April, but there's intense

opposition to a potential deal in Congress with most Republicans and some Democrats

arguing that Iran will use any agreement as a pretext to keep efforts going to build nuclear weapons.

House Speaker John Boehner made his reservations known publicly when he invited Israeli Prime

Minister Benjamin Netanyahu to speak to Congress last week without consulting the Obama administration.

And this week, 47 Republican senators sent a letter to Iran's leaders in which they explained

the role of the Senate in approving treaties.

The letter argued that any agreement short of a treaty could be revoked

by a future Republican president. Both acts started a wide-ranging public debate about the proper

constitutional roles of the president and Congress in directing foreign policy and joining me to proper constitutional

issues are two of the world's leading experts on the questions and also good friends of our
