Former national security adviser Susan Rice ripped into President Trump on MSNBC Wednesday over his blaming the Obama administration, in which she served, for rising tensions in Iran.

This is another series of despicable lies by President Trump. The fact that ... he remains obsessed with President Obama just shows President Trump's extreme weakness and insecurity."

Catch up quick: In an address on Wednesday responding to Iranian missile strikes on Iraq bases where U.S. troops are stationed, Trump argued the Iranian nuclear deal was "foolish" and claimed that the missiles fired were funded by the Obama administration.

Rice responded: "The facts about the Iran nuclear deal are that it effectively halted and rolled back Iran’s nuclear program. In the years since the signing of the deal in 2015 up until President Trump’s unilateral withdrawal, abandoning our allies against the advice of his advisers, there were no proxy attacks by Iranian proxies on U.S. personnel in Iraq."
