Former President Barack Obama is again trying to get involved in a high-stakes event led by President Donald Trump.

Obama took a shot at Trump’s war with Iran, arguing his government “got it done without firing a missile” in a robust defense of the 2015 Iran nuclear deal.

The Late Show presenter Stephen Colbert presented the new tape from an interview shot in April at the Obama Presidential Center in Chicago.

In an unprecedented moment, Colbert probed the ex-president on whether he ever thought of “military action” as a “tool” in his negotiations with Iran.
