From President Trump's move to decline to certify Iran as compliant with the international nuclear agreement to the ongoing back and forth over North Korea's nuclear program, it was an important week for global affairs.

On the domestic side, Thursday, the president signed an executive order that changed Obamacare's insurance regulations, then HHS issued a late night directive eliminating subsidy payments to insurance companies. What impact will those actions have on efforts to fix Obamacare?

Secretary of State Rex Tillerson will join the program to discuss the administration's new way forward with the Iran nuclear agreement and the administration's tougher line on Iran, a country which Mr. Trump has repeatedly linked to terror organizations and accused of supporting destabilizing regimes like the one in Syria.

Sen. Lindsey Graham, R-South Carolina, will weigh in on the Senate's role in addressing Mr. Trump's new Iran policy. Graham, who has recently spent time golfing with the president, will also offer his perspective on the president's relationship with Congressional Republicans after frustrating legislative setbacks throughout the year.

Israeli Prime Minister Benjamin Netanyahu – a longtime opponent of the Iran nuclear deal, will join the broadcast to react to the Trump administration's actions.
