As previously undecided senators one by one came out in support of the agreement over the past month, references in their statements to the views of the other P5+1 governments involved in the negotiations Russia, China, Britain, France and Germany were strikingly common.
Many of them attended a briefing by ambassadors from those countries in early August.
When she announced her support for the deal on August 6, Sen. Kirsten Gillibrand (D-N.Y.) said, In a meeting earlier this week, when I questioned the ambassadors of our P5+1 allies, it also became clear that if we reject this deal, going back to the negotiation table is not an option.
Four days later Sen. Amy Klobuchar (D-Minn.) said she had asked the ambassadors of the five other countries involved in the talks detailed questions about what their countries and others would do if Congress does not approve the agreement.
[N]ot one of them believed that abandoning this deal would result in a better deal, she said. Instead, international consensus would splinter, sanctions would unravel and Irans nuclear program would be left unconstrained.
On Aug. 13, Sen. Al Franken (D-Minn.) also referred to the ambassadors briefing.
Yes, Jeff Sessions, when he was a Senator met with a lot of people including Russian Ambassadors...it was his JOB at that time...
