President Barrack Obama's former Chief official White House photographer, Pete Souza, shared a photo on instagram and he wrote:
"President Obama meets in the Situation Room for the first time with his national security team on Jan. 23, 2009. During eight years I documented probably more than 100 meetings in the Situation Room. Not sure if it gets much use now."
He may have written this to tell that during Trumps administration the Situation room has been less used.
