Former US national security adviser Condoleezza Rice said that she had to yell at then President George Bush not to return to the White House, a potential terrorist target, following the 9/11 attacks, The Daily Mirror reported on Monday. Rice's comments came in a documentary film entitled 9/11: State of Emergency, which is scheduled to air on British television on Saturday, the nine year anniversary of the deadly attacks.According to Rice, Bush insisted on returning to Washington from Florida following the attacks, prompting her to order him away from the White House."I said, 'You cannot come back here. The United States of America is under attack, you have to go to safety. We don't know what is going on here.' He said, 'I'm coming back.' I said in a raised voice, and I had never raised my voice to the President before, I said, 'You cannot come back here.' I hung up."Rice also discussed a bunker beneath the White House which "non-essential" people were forced to leave in the aftermath of the attacks because of overcrowding.
