NEW YORK - David Bloom was a rising star at NBC News, a weekend anchor on "Today" who traveled from the White House to become one of the most frequently-seen TV reporters on the Iraqi desert.
The network was shocked Sunday when the 39-year-old Bloom died suddenly in Iraq, not from a battlefield injury but from an apparent blood clot that caused him to collapse and never regain consciousness.
Bloom was about 25 miles south of Baghdad and packing gear early Sunday to travel with the U.S. Army's 3rd Infantry Division when he was stricken. He was airlifted to a nearby field medical unit and pronounced dead from a pulmonary embolism, said Allison Gollust, a spokeswoman for NBC News.
Bloom was the second American journalist to die while covering the war. Michael Kelly, editor-at-large for The Atlantic Monthly and a columnist for The Washington Post, was killed Thursday night along with a U.S. soldier when their Humvee plunged into a canal.
Kelly had also been traveling with the 3rd Infantry.
NBC News had built a special vehicle, dubbed the "Bloom-mobile," to send strikingly clear pictures of him riding atop a tank through the Iraqi desert. He reported memorably on the sandstorms that briefly delayed American forces.
"He was both a genuinely nice guy and an incredibly tenacious reporter," NBC News President Neal Shapiro said. "He wouldn't be beaten on a story. He always kept us in the game."
From the Iraqi desert, Bloom reported on what the American forces were doing militarily, but he also took the time to convey what their lives were like there, including the meals they were eating and what it was like trying to work in the middle of a sand storm.
"He was a rising star here," Shapiro said.
Bloom, a native of Edina, Minn., lived in the New York area with his wife, Melanie, and three daughters. After attending Pitzer College in Claremont, Calif., Bloom started his career as a local government reporter for WKBT-TV in La Crosse, Wis. He worked in Kansas and Florida before joining NBC News in Chicago in 1993 and moving to Los Angeles in 1995.
He became a White House correspondent for NBC in 1997, during the Clinton administration. He reported on presidential races, the O.J. Simpson trial, the Washington-area sniper shooting and the Sept. 11 terrorist attacks.
Former President Clinton said Sunday that Bloom's "integrity and good humor will be missed."
"David Bloom was a smart, energetic professional whose enthusiasm for the job was evident in every question he asked and every story he covered," Clinton said.
Shaken NBC colleagues, including "Today" co-anchor Soledad O'Brien, paid tribute on the network's broadcasts Sunday. "It's a hard morning for all of us," Katie Couric said.
Bloom, who had no apparent health problems, was indefatigable during the Gulf War. He reported at all hours for NBC News broadcasts, and also for the cable outlets MSNBC and CNBC.
On the Monday after the war started, Bloom delivered live reports at 2:22 a.m. ET for MSNBC, at 6:55, 7:09 and 8:04 for "Today," at 10:43 for NBC, 10:47 for MSNBC, 11:12 for NBC, 12:31 p.m. for NBC, 12:36 and 2:33 for MSNBC, at 6:37 for NBC's "Nightly News," and at 8:07 and 9:35 again for MSNBC, according to The Washington Post.
"Given the fact that we're filing at all hours of the day and night, you try to pace yourself and get a little sleep," Bloom told the Post. "You're sleeping with your knees propped up around you."
That may have been a risk factor: blood clots frequently form in legs when they've been immobilized and travel through the body, said Dr. Harold Palevsky, chief of pulmonary critical care with the University of Pennsylvania health system.
Dehydration can also be a factor. Palevsky said Army medics, trained and equipped to stop bleeding, may have been less prepared in the desert for a pulmonary embolism.
ABC News President David Westin said his network was deeply saddened by Bloom's death, calling him "a great journalist and a vigorous competitor; he made all of us better by the standards he set."
Bloom's brother Jim, of Seattle, said funeral arrangements were pending Monday but the service would likely be at the end of the week in New York. The family issued a statement saying Bloom "touched so many people throughout his life and his work, but none more than his family. We will miss him forever."
