WASHINGTON (AP) -- The Obama administration is defending Iran's steps to implement the nuclear deal to skeptics in the U.S. Senate.
Republicans say economic sanctions should not be lifted in light of Tehran's recent ballistic missile tests in violation of a U.N. Security Council resolution.
Sen. Kelly Ayottere and 35 other Republican senators wrote the president Thursday noting the recent ballistic missile tests. Democrats at a Senate Foreign Relations Committee hearing want zero tolerance of violations of the nuclear deal or any other international obligations.
Republican committee chairman, Sen. Bob Corke, says the agreement is off to a "terrible start."
Stephen Mull is lead coordinator for implementation of the deal. Mull says Iran has begun removing thousands of enriched centrifuges and is shipping low-enriched uranium out of Iran.
