Corker said although he is pleased that a deal was reached, he is worried about enforcing the agreement with Iran. He said that the Obama adminsitration has been "long on announcements, but short on follow through."
"My greatest concern is seeing follow through here," he said.
He said that Iran is taking advantage of a weak administration.
"They view this administration as week," Corker said. "They see this as their window of opportunity."
Corker said that there will likely be members of Congress who will still look to strengthen sanctions against Iran despite the new deal.
