President Trump spent two hours Thursday meeting with his national security team in a secure conference room at the Pentagon known as "the tank" to get an update on flashpoints around the globe.

Vice President Mike Pence, Secretary of State Rex Tillerson, and Treasury Secretary Steve Mnuchin were among the members of Trump's team who traveled across the Potomac River for the session, which was hosted by the Defense Department's top civilian and military leaders, including Defense Secretary Jim Mattis, newly-confirmed Deputy Defense Secretary Patrick Shanahan, Joint Chiefs Chairman Gen. Joseph Dunford, and Joint Chiefs Vice Chairman Gen. Paul Selva.

The meeting was a chance for the president to hear first-hand about world hot spots, including North Korea, Iraq, Syria, Iran and Afghanistan, according to Pentagon officials.

Chief Pentagon spokeswoman Dana White told reporters afterward that the meeting was a "global overview," and indicated no decisions were made during the session.

The president made no formal public comments during his second visit the nation's military headquarters, but he did answer a shouted question on his arrival as he ascended the steps of the Pentagon's river entrance.

Asked if the U.S. would be sending more troops to Afghanistan, which is expected to be part of the Mattis' new, revised strategy for the nearly 16-year-log war, Trump said, "We'll see." He added, "and we're doing very well against ISIS. ISIS is falling fast, very fast," according to a pool report.

Trump later tweeted a video of himself and other officials shaking hands with various enlisted troops who lined the hallway as the president departed for the short trip back to the White House.
