AP (emphasis mine):
White House press secretary Dana Perino called the charges of stifling dissent “nonsense.”
“The president welcomes robust and healthy debate,” she said. “He has many members of his administration that represent different viewpoints. He has dissenting views on a variety of issues that get worked out through a policy process that is usually not fed out in the press.”
“There’s no one in the administration that is suggesting other than a diplomatic approach to Iran,” Perino said.
Of course not.
