with Iranian government:
"Sen. Chris Murphy of Connecticut and other Democratic senators had a secret meeting with Iranian Foreign Minister Mohammad Jahad Zarif during the Munich Security Conference last week, according to a source briefed by the French delegation to the conference. Murphy’s office did not respond to repeated requests for comment by press time."
"Such a meeting would mean Murphy had done the type of secret coordination with foreign leaders to potentially undermine the U.S. government that he accused Trump officials of doing as they prepared for Trump’s administration. In February 2017, Murphy demanded investigations of National Security Advisor Mike Flynn because he had a phone call with his counterpart-to-be in Russia."
“Any effort to undermine our nation’s foreign policy – even during a transition period – may be illegal and must be taken seriously,” Murphy said in 2017"
