() President Donald Trump is expected to make an announcement from the Oval Office Tuesday morning.

The subject of the announcement is not yet known.

Trump will speak from the Oval following his appearance at a meeting of top military brass called by Secretary of Defense Pete Hegseth.

Hegseth summoned military leaders, including generals stationed overseas, to Quantico, Virginia, where he gave a speech on changes he wanted to see in the armed forces. Hegseth said he wanted increased physical fitness standards, an end to complaints about toxic leadership, an end to diversity and inclusion efforts and an end to focus on climate change.

Trump also spoke at the gathering, where he blamed President Joe Biden for the military’s struggles to meet recruiting goals, repeated his claim that he has ended multiple wars and touted an end to political correctness in the military.
