President Joe Biden is in danger of allowing Iran to acquire nuclear weapons under the cover of the lengthy diplomatic process, according to a senior Senate Democrat.

“We cannot allow Iran to threaten us into a bad deal or an interim agreement that allows it to continue to build its nuclear capacity,” Senate Foreign Relations Chairman Bob Menendez said on the Senate floor. “Nor should we cling to the scope of an agreement that it seems some are holding on to for nostalgia’s sake.”
