Reporter: When it entered US airspace, has it changed it's course in any way?
Pentagon: The balloon has changed it's course, which is why we are monitoring it.
Pentagon: Considering the size of the payload…looking at the potential for debris and the impact on civilians on the ground, or property damage…right now we are going to continue to monitor [not shoot down] and review options.
Pentagon: It will probably be over the United States for a few days.
Reporter asked about similar, previous incidents.
Pentagon: That information is classified…I can [only] confirm that there have been other incidents where balloons did come close to, or cross over US territory.
Reporter: In the past, has [a balloon] flown over other sensitive areas such as military bases?
Pentagon: That information is classified.
Reporter: Is the balloon leaving anything in it's wake, like sensors?
Pentagon: I'm not going to get into intelligence…we do know that it's a surveillance balloon.
>if this were reversed and America had a balloon in China..I think before they could confirm either way it would have been shot down
True, but China also has no concern over what would happen to people or property on the ground.
Jean-Pierre: [Bide] was briefed on [the balloon] on Tuesday.
Jean-Pierre: We acted immediately to take all necessary steps to protect against foreign intelligence collection of sensitive information.
