A fourth UFO has been shot down over North America after airspace was again temporarily shut down.
It is the third such incident in three days across the US and Canada, amid White House fears of possible foreign spying.
Senator Jack Bergman said he'd been told by the Department of Defense on Sunday that the military had "decommissioned" another "object" over Lake Michigan-Huron.
In a tweet, he added: "I appreciate the decisive action by our fighter pilots. The American people deserve far more answers than we have."
Congresswoman Elissa Slotkin said: "We’re all interested in exactly what this object was and its purpose."
The Federal Aviation Administration issued a notice at 11am local time, confirming flights in the area had been restricted for unspecified reasons.
Two hours later, it said the airspace was re-open.
The US and Canada have now brought down four high-altitude airborne objects this month, including one the US said was sent deliberately by China for surveillance.
The so-called 'spy balloon' is thought to have floated across 150 nuclear weapons silos at the Malmstrom Air Force Base, in Montana, and US Strategic Command, in Nebraska, which controls the country’s nuclear force.
It remained airborne from January 28 to February 4 and was eventually shot down off the South Carolina coast.
Three airports were shut and airspace was closed off the coast of North and South Carolina as the military carried out the operation on Saturday.
The military is recovering debris which is spread over seven miles, so they can investigate the balloon further.
The White House said the object was "the size of a small car" and posed a "reasonable threat" to commercial flights.
The UK Defence Secretary Ben Wallace said he would have similarly brought down the balloon had it threatened the UK.
Meanwhile, yesterday Canadian PM Justin Trudeau ordered the "take down" of another UFO which he said had floated into Canadian airspace.
It came down over the Yukon, he confirmed.
He tweeted: "Canadian and U.S. aircraft were scrambled, and a U.S. F-22 successfully fired at the object."
On Friday a different object was shot down while flying at 40,000ft over the coast of Alaska and had reached speeds of 40mph.
It was travelling towards the North Pole before being shot down.
China says the UFO taken down over South Carolina was carrying weather equipment.
As reported earlier today, Beijing is allegedly preparing to take down an object spotted over the water near the port city of Qingdao.
