When someone takes the oath, they publicly affirm their allegiance to the Constitution of the United States.

Said another way, we do not pledge loyalty to a person or party, not in this country.

Think about that for a moment. Our oath is a promise to protect and defend our Constitution.

It is a promise to faithfully serve the United States and our fellow citizens.

Our oath is ambitious, and it is principled.

I'm Chuck Rosenberg, and I have had the privilege of taking that oath many times throughout my career in federal law enforcement.

And now, on my podcast, The Oath, I speak with others who took an abided by that same promise.

My guests spent decades in public service. People like Deputy Attorney General Sally Yates, FBI Director Jim Comey,

the United States Attorney, Preet Barar, and White House Homeland Security Advisor Lisa Monaco, among others.

If you have not heard those interviews from last season, please go back and listen. I think you'll enjoy them.

Coming up on this season, we speak with other talented and dedicated public servants, such as Rob Spencer,

the federal prosecutor who led the 9-11 case.

We needed to treat this as a regular murder case, except with nearly 3,000 victims.

Retired four star Admiral William McRaven, a Navy SEAL for 37 years, and the commander of the US Joint Special Operations Command.

Send me. Send me to Iraq, send me to Afghanistan, send me to Somalia, send me to North Africa. Send me where the nation needs me. Just send me.

Kathy Remler, Enron Prosecutor, and White House Counsel to President Barack Obama.

When you are the White House Counsel, you are representing the office holder, the person who embodies the presidency, the office itself.

You're not representing an individual person.

MSNBC's own Joyce Vance, the United States Attorney for the Northern District of Alabama.

Good prosecutors understand that we have to always be open to examining our behavior to make sure that the system works the way it's intended to.

Retired four star Admiral Jim Stavridis, the Supreme Allied Commander of NATO.

People would say, you know, you're a way. You miss so many Christmases, and that's the price you pay for the right to serve.
