Rosen's first job after graduating from journalism school was as a producer for the New York television channel
NY1. His on-air career began when he was hired by Roberto Soto at News 12–The Bronx. Initially Rosen was a
one-man-band street reporter at News 12-The Bronx and was eventually promoted to
anchorman. He also served as camera operator, editor and producer for that network. He also worked at
CBS News as a researcher for lead anchor
Dan Rather. Rosen worked for
WREX-TV, the local NBC affiliate in
Rockford, Illinois. Rosen joined Fox News as an on-air correspondent in February 1999. According to his Fox News biography, he reported "from 49 states and more than three dozen foreign countries across five continents." Rosen left
Fox News at the end of 2017 in the context of multiple claims that he
sexually harassed coworkers. Interviews with eight of his former colleagues revealed allegations of multiple instances in which Rosen made "overt physical and sexual overtures." Reporting for
Sinclair Broadcast Group on December 5, 2019, Rosen irked Speaker of the House
Nancy Pelosi when he asked her if she "hates President Trump" as she was leaving a press conference regarding the
impeachment inquiry against Donald Trump. Pelosi replied to Rosen, “I don’t hate anybody.” She then returned to the lectern and stated: “As a Catholic, I resent your using the word hate in a sentence that addresses me. I don’t hate anyone. So don’t mess with me when it comes to words like that.” In June 2022, as a Newsmax reporter covering a White House briefing where actor
Matthew McConaughey made an impassioned plea for gun control following the
Robb Elementary School shooting in McConaughey's home town of Uvalde, Texas, Rosen asked McConaughey if he was "grandstanding." In July 2024, as a Newsmax White House correspondent Rosen shouted out a question about then-President Joe Biden’s cognitive health to White House press secretary
Karine Jean-Pierre. "Is he disabled? Is the president disabled?" Rosen asked. Reportedly, Jean-Pierre snapped back at Rosen for shouting out the question. Rosen later recounted on Newsmax,
Greg Kelly Reports about being "blackballed" from asking questions at the White House in 2022 after questioning then-President Biden about his cognitive fitness. ==Books==
