The Pentagon is now monitoring a Chinese spy balloon moving over the continental U-S and expected to be in U-S air space for a few days. In a committee hearing, Senator Marco Rubio says China has been "weaponizing" the U-S for years. He's tweeting today it's a mistake not to shoot the balloon down which he says has a large payload of sensors roughly the size of two city buses the ability to maneuver independently. Officials say they decided against shooting it down to avoid debris hurting anyone on the ground. China claims the balloon is being used for weather research and blown off course.
