In Afghanistan, his reporting exposed how the C.I.A. made monthly cash drops at the office of President Hamid Karzai; provided a detailed account of an attack by Afghan soldiers on American troops; and dubbed the country's first international boxing match the "Squabble in Kabul" (like the fight, the name has not gone down in boxing history). Mr. Rosenberg also managed to slip in a few fly-fishing trips to the mountains in northeastern Afghanistan, where he was thoroughly outdone by Afghan children who used bamboo sticks for poles.
Since leaving Afghanistan, his focus has been on the United States, reporting on national security in Washington and working as an investigative reporter. He covered the Jan. 6, 2021, attack on the Capitol and its fallout, explored the conspiratorial turn among some Republican voters and wrote about the Pentagon's push to develop weapons powered by artificial intelligence.
Mr. Rosenberg previously worked for The Wall Street Journal and The Associated Press. In addition to the Pulitzer Prize, he has won three George Polk Awards, a Gerald Loeb Award and was twice a finalist for the Pulitzer Prize – once in international reporting as part of a team of Times reporters covering the Islamic State, and another time for his work on Cambridge Analytica and data privacy.
He was born in New York and graduated from McGill University in Montreal.
