U.S. military tracking ANOTHER balloon: Pentagon scrambles jets to investigate high-altitude object of 'unknown origin' over Colorado

The U.S. military is tracking yet another balloon over the western United States, a year after a Chinese spy balloon provoked a diplomatic crisis.

The military dispatched aircraft to investigate the situation, CBS news reported, adding that it has not been determined to be a threat.

Like the spy balloon that entered U.S. airspace and slowly made its way across the U.S., the current balloon was spotted in Colorado. 

The spy balloon that entered U.S. airspace over Alaska in January eventually flew over a U.S. military base in Montana. It wasn't until it was over the Atlantic that the military shot it down off the coast of South Carolina, citing security risks of downing it over land. 

That in turn provoked Beijing, which vowed countermeasures, adding yet another strain a relationship already battered by trade practices, tariffs, Taiwan, human rights, and China's ties with Russia before President Vladimir Putin launched his Ukraine invasion.

Republicans criticized President Joe Biden for not having it downed sooner. The incident prompted a period when the military shot down other unidentified objects.

The earlier incident forced Secretary of State Antony Blinken to cancel a planned trip to China while criticizing it as an 'irresponsible act.'

Biden in June said he didn't think 'the leadership knew where it was and knew what was in it and knew what was going on,' calling it 'more embarrassing than it was intentional.'

He then met with Chinese President Xi Jinping in San Francisco in November in an effort to put the U.S.-China relationship on a firmer footing. 

The White House had no immediate comment. 

The balloon is being carried east by the Jet Stream, which boasted near record wind speeds last week, allowing a Virgin Atlantic transatlantic flight to top 800 miles per hour.

It is crossing while Biden already has his hands full with other foreign policy challenges. On Friday he appealed to House Republican leaders to bring lawmakers back to vote on a stalled package to provide $60 billion to aid Ukraine.

He met this week with the wife of slain Russian opposition leader Alexei Navalny. There are reports Ukrainian forces are rationing ammunition while facing continued Russian attacks. And Israel's war on Gaza is leading to continued civilian casualties while posing political problems for Biden as he faces more primary election tests.
