Since joining ABC News in 2004, Weir has traveled the planet to cover breaking news and uncover global trends. His in-depth reports on the economic rise of China and India were signature features on "Good Morning America," while "World News" devoted extraordinary air time to his storytelling from Africa, the Middle East and the South Pacific.
He waded through the floodwaters of New Orleans after Hurricane Katrina, dodged Taliban bullets in Afghanistan in 2010 and led the network's coverage of "Iraq, Where Things Stand" at the height of the American troop surge.
Weir has anchored several launches and landings of the space shuttle, was the first American to broadcast live from Tibet and led off 2007's Earth Day special with an unprecedented underwater live report from the Great Barrier Reef.
Domestically, Weir's reporting often focuses on innovative solutions to America's biggest problems, from border security and new energy to health care and education reform to the cause and effect of 2009's "Great Recession."
In June 2007, Weir was named anchor of the ABC News magazine "iCaught," and as a writer and anchor, he produced special hours for the network on topics ranging from religion to brain science to the rise and fall of General Motors.
Weir lives in New York with his wife and daughter and sincerely believes he could escape from prison if the need ever arises.
