The U.S. military is tracking a high-altitude balloon over the Western United States, two U.S. officials confirmed to Fox News on Friday.
It was spotted by U.S. military aircraft and determined to not be a threat.
The origin of this balloon and its purpose are not yet known, the two officials said.
The balloon is drifting east in the jet stream.
This is a developing story.
