AP: On Capitol Hill, there was a predictably mixed reaction to President Donald Trump's decision to withdraw from a nuclear accord with Iran.

While some members of Congress expressed concern, saying the president made a mistake, other Senators praised the move.

"I'm glad we are out of it." Sen. Marco Rubio said after the president's announcement. "Iran ... is more dangerous today than it was the day before the deal was signed."

Rubio, who ran against Trump in the Republican presidential primary, said he is not surprised President Trump made the decision to withdraw from the deal, as he had made a promise to do so during the presidential campaign.

Sen. Chris Coons, who sits on the Senate Committee on Foreign Relations, said the decision makes the U.S. "less safe, less secure by weakening our bonds with our allies."

The 2015 agreement had lifted most U.S. and international sanctions against Iran. In return, Iran agreed to restrictions on its nuclear program that would make it impossible to produce a bomb, along with rigorous inspections.
