At his weekly news conference Thursday, Speaker John A. Boehner threw cold water on an emerging Senate Iran bill, saying it was too early to speculate on the legislation while slamming Iran for statements it has made throughout the nuclear negotiating process. “We’ll see if there is an agreement, we’ll see what comes of the Corker bill that comes out of the Senate and then we’ll take it from there, but it’s too early to speculate on whether we can or can’t,” Boehner said, responding to a question about whether Congress could stop a deal on Iran’s nuclear program.
