Secretary of State John Kerry on Wednesday said American allies "won't be swayed or intimidated by a tweet" from President-elect Donald Trump, who has repeatedly weighed in on foreign affairs despite not yet taking office. In an exclusive interview with NBC's Andrea Mitchell, Kerry said he would not get into a "debate" with Trump, but suggested U.S. allies have been "affected" by the president-elect's recent commentary on U.S.-Israeli relations and other sensitive foreign policy issues.
