Secretary of State Marco Rubio says he is acting director the U.S. Agency for International Development, following days of upheaval at USAID as the Trump administration froze many of its programs.

In its first two weeks, President Trump's administration has made significant changes to the U.S. Agency for International Development.

The U.S. Agency for International Development is at the center of a political firestorm after the Trump administration indicated it will shut it down as an independent agency and possibly move it under the U.S. State Department in a larger effort to crack down on federal bureaucracy.
