Republican Rep. Mike Lawler of New York says the US should "hold the Chinese to account" for facilitating Iran's illicit oil trade as President Donald Trump pushes an economic "D-Day" against Tehran. Lawler, a member of the House Foreign Affairs and Financial Services committees, also calls the $40 trillion US debt a "crisis" and says Congress needs a bipartisan solution. He talks to Bloomberg's Kailey Leinz.
