WASHINGTON — Secretary of State Mike Pompeo says his Obama-era predecessor John Kerry has been “actively undermining” U.S. policy on Iran.

Late Thursday, President Donald Trump had accused Kerry of holding “illegal meetings” with the Iranian government.

Pompeo said he would leave “legal determinations to others” but slammed Kerry as a former secretary of state for engaging with “the world’s largest state-sponsor of terror” and telling Iran to “wait out this administration.”

Pompeo contended Friday: “You can’t find precedent for this in U.S. history.”

Kerry was an architect of the Iran nuclear deal that Trump withdrew from in May and has met several times with Iran’s foreign minister since leaving office.

Meetings between a private U.S. citizen and foreign official are not against the law and not necessarily inappropriate or a violation of federal regulations.
