US Secretary of State Marco Rubio welcomed the disbanding of USAID, saying it will improve the effectiveness of foreign assistance

Marco Rubio has said that disbanding USAID will allow a more efficient approach to foreign assistance, but a study published in The Lancet estimates it could cause an extra 14 million deaths, especially among children. Funding cuts affect essential health programs, and State Department officials dispute the study's conclusions. Aid groups warn the rapid shift has already had devastating effects on global humanitarian assistance.
