Days after the Trump administration launched dozens of missiles at a Syrian air base, "Fox News Sunday" has an exclusive interview with one of the key men who helped President Trump plan the airstrikes.

National Security Advisor H.R. McMaster joins Chris Wallace to break down the attack and the crucial next steps.

The much-anticipated interview will be McMaster's first since he replaced Michael Flynn as Trump's national security advisor.

In addition to McMaster, Wallace will also sit down with Sen. John Cornyn (R-TX) and Sen. Ben Cardin (D-MD) on what's sure to be a big edition of "Fox News Sunday."

Watch the interview with McMaster above.
