The new director of the Pentagon’s All-domain Anomaly Resolution Office (AARO) confirmed to lawmakers on Tuesday that the U.S. is investigating what he characterized as “some very anomalous objects,” while providing an update on the Defense Department’s ongoing investigations into unidentified anomalous phenomena (UAP).

Dr. Jon Kosloski, who assumed the role of Director of AARO in August, made the comments during a hearing held by the Senate Armed Services Subcommittee on Emerging Threats and Capabilities overseen by U.S. Senator Kirsten Gillibrand (D-NY).

In his opening statements, Kosloski pledged that his office would continue to share information about AARO’s findings at the unclassified level, discussing several UAP cases his office has investigated, including a series of incidents which AARO says have now been resolved.
