U.S. Secretary of State Mike Pompeo says former Secretary of State John Kerry "can't seem to get off the stage" of foreign policy.
Pompeo leveled his latest blast at Kerry Wednesday night on Fox News.
Pompeo ripped Kerry last week after the Obama administration's chief diplomat met with Iran's foreign minister several times talk about the Iran nuclear deal President Trump abandoned.
Earlier this week, Florida Republican Senator Marco Rubio asked the Justice Department to determine whether Kerry's meeting broke the law.
A federal law bars unauthorized people from negotiating with a foreign government about any disputes with the U.S.
Another law requires people who act on behalf of foreign governments to disclose details of their actions.
