DOD is sending 1,500 active-duty service members and additional air and intelligence assets to the southern border to augment troops already conducting enforcement operations in that region, Acting Secretary of Defense Robert Salesses said.

The U.S. Fish and Wildlife Service proposed the monarch butterfly be afforded new protections under the Endangered Species Act. 

President Donald J. Trump named Robert Salesses as acting secretary of defense pending the confirmation of Pete Hegseth for the position.

President Donald J. Trump said during his inaugural address as 47th president that he has "no higher responsibility than to defend our country from threats and invasions, and that is exactly what I am going to do."

About 7,800 National Guard troops are on duty during the 60th Presidential Inauguration, continuing of a legacy that began in 1789 when their predecessors escorted George Washington to the first inauguration.

The American military has an asymmetrical advantage over any possible adversary with its special operations community, and the processes are in place to keep that advantage going well into the future.
