After college, Trohan went to New York City to work but "didn't like it" and returned to Chicago. In 1927, Trohan went to work at the for the
City News Bureau of Chicago (1927–1929). In 1947, Trohan became "executive director" of the
Tribune's Washington bureau through 1949.
Douglas MacArthur In 1949, Trohan became Washington bureau chief (or "director") until 1969. In 1951, Trohan was known for ferreting out the fact that Truman planned to fire General
Douglas MacArthur, the commander of
UN forces in Korea. When Truman found out that Trohan knew about his plan, he publicly announced his decision via General
Omar Bradley and robbed Trohan of the scoop. He experienced censorship during World War II as well.
"Washington Report" From 1951 to 1968, Trohan also filed a radio broadcast, "Washington Report." In 1959, he accompanied US President
Dwight Eisenhower on a three-continent tour. In 1969, he retired from his position as Washington bureau chief and, on December 31, 1971, from his radio and column.
Richard Nixon Trohan was a long-time "intimate journalist friend" of
Richard Nixon. In 1953, he wrote Nixon (then the vice president) a letter that warned him against U.S. Senator
Joseph McCarthy. {{cite book {{cite book {{cite book {{cite book ==Personal life==
