Examples of Pentagon in a Sentence

1. Defense Ash Carter:

   Eric served as my first chief of staff at the Pentagon, and it has been a privilege over the course of my career to work alongside him and watch him develop into one of our country's most knowledgeable, dedicated, and experienced public servants, i know he will strengthen our Army, build on its best traditions, and prepare our ground forces to confront a new generation of challenges.

2. John Campbell:

   If errors were committed, we will acknowledge Doctors Without Borders. We will hold those responsible accountable, and we will take steps to ensure mistakes are not repeated, we will await the outcome of the( The Pentagon) investigation to provide any additional updates, and we will share the results of the investigation once it is complete.

3. Christopher Suprun:

   That story exhibits a reckless disregard for the truth. I never claimed to be a first responder on 9-11 with the Manassas Park Fire Dept. I was a volunteer firefighter at the time for the Dale City Fire Dept. when I responded to the attacks at the Pentagon.

4. Floyd Abrams:

   We cannot predict today which publication will so inflame the president that he would seek to block publication of news, if he could, but we can expect that that day will occur. When it does, the Pentagon Papers case will stand as a powerful barrier against any effort to suppress publication.

5. John Sopko:

   How many people want to talk about Afghanistan at the Pentagon? How many people want to talk about Afghanistan at State, or AID? Not many, and you know this report, with its companion report, is the only official US government report that’s public … on the 20 years spent in Afghanistan. To me, I’m very glad that we were able to do this, but I’m an inspector general. You would think the Department of Defense or Department of State or USAID or the National Security Council would have come out with something official on the 20 years there.
