IRAN NUCLEAR TALKS

Secretary of State John Kerry said he is in “utter disbelief” over the letter to Iran’s leaders authored by Sen. Tom Cotton and signed by 46 other Republican senators. In testimony before the Senate Foreign Relations Committee yesterday, Kerry admitted that the deal with Iran would not be “legally binding,” but said such “executive agreements” were a “necessary tool of American foreign policy.” [New York Times’ Michael R. Gordon]

Some Republican senators admitted to being surprised by the backlash to the letter, with Senate Armed Services Committee chair John McCain acknowledging that they “probably should have had more discussion about it.” [Politico’s Burgess Everett]

Officials fear a nuclear arms race in the Middle East, triggered by regional rivalry, if Iran is allowed to maintain nuclear capability. [Wall Street Journal’s Jay Solomon and Ahmed Al Omran]

UKRAINE and RUSSIA

The Minsk agreement appears to be holding, but remains fragile, NATO Secretary General Jens Stoltenberg said yesterday, calling for improved monitoring of the ceasefire.

HILLARY CLINTON’S PRIVATE EMAILS

Investigations into Hillary Clinton’s use of private email have been launched or are being weighed by at least three House committees. [Politico’s Jake Sherman and John Bresnahan]  Meanwhile, several Democrats have spoken out in support of the former secretary of state, stating she did not break any laws and accusing Republicans of carrying out politically motivated attacks. [The Hill’s Mike Lillis and Jonathan Easley]

The Wall Street Journal editorial board questions how Clinton carried out her job as secretary of state without, as she suggests, “sending a single email that had classified information in it.”
