Three Obama officials who worked closely on the Iran nuclear deal, one of whom is still in touch with Iranian government officials, traveled to Capitol Hill to brief congressional Democrats about the situation. Those former officials said would not say if they passed information from Iranian government officials to members of Congress. Rather, they said they focused on educating members about their experience working with Iranian leaders and how Tehran reacts to economic pressure.

Several former officials who spoke to The Daily Beast stressed that their discussions with their Iranian contacts were “normal.” But in other corners, these kind of talks cause alarm. A Republican congressional aide who works on Iran policy told The Daily Beast the conversations may run counter to the Trump administration’s messaging to the Iranian government.

“It’s not just about what they were saying to the Iranians,” the aide said. “It’s about what they were saying to their political allies back here in the U.S. Their strategy was to divide and isolate the Trump administration just as the Trump administration was trying to re-establish deterrence with Iran. In the current highly partisan political environment, the only safe course is to signal national unity—and they contributed to eroding that at home and abroad.”
