Skeptical members of Congress – and the general public – might not trust the administration when it says it will prevent the Islamic Republic from building a nuclear weapon. And they certainly don’t trust the Iranians. So the White House is asking them instead to put their faith in science.

The White House is planning to roll out more of its science-driven message next week in its ongoing bid to stop Congress from moving to block the deal. The idea is to convince Congress and the public that, hey, the scientists think this is a good deal, so they should too.

Some hardliners will never accept the deal, White House Press Secretary Josh Earnest said in an interview on Friday. “But for every other member of Congress — presumably including some Republicans — that is attempting to evaluate this deal on the merits, I would anticipate that scientific data would be persuasive for them.”
