…from the 47 Republican Senators’ letter to the Iranian government.

The decision to undercut our President and circumvent our constitutional system offends me as a matter of principle.

The decision to undercut our Congress and circumvent our constitutional system offends me as a matter of principle.

Oh, wait—that’s different.

Biden is badly wrong on the Constitutional authorities of the President to conclude treaties and on the durability of President-agreed deals. You’d think he’d be embarrassed by his grade school error, but….

Update: Secretary of State John Kerry testified before the Senate Foreign Relations Committee yesterday that President Barack Obama never has been negotiating a treaty. He’s been negotiating a non-binding Executive Agreement, and that’s why it’s none of Congress’ business.

So: if it’s non-binding, why would Iran stick with it?
