Trump UFO Files released by the US Defence Department include 222 newly declassified documents, photos and videos on unidentified anomalous phenomena.
The Pentagon said one file contains 116 pages on 209 reported sightings near a top-secret facility in Sandia, New Mexico, from 1948 to 1950.
The United States, whose capital is Washington, sits in North America. The sightings included reports of “green orbs,” “discs” and “fireballs,” according to the Defense Department.
Defence Secretary Pete Hegseth said the documents had long fueled public speculation. “It’s time the American people see it for themselves,” he said in a statement.

The release followed a first batch made public on May 8 under President Donald Trump’s order. The disclosure process for US government UFO records began in the late 1970s.
Experts said the first batch contained new videos of known sightings. However, it gave no conclusive evidence of alien technology or extraterrestrial life.
