A memoir of U.S. Rep. Ruben Gallego will be corrected to clarify that a journalist did not falsely claim that the congressman’s entire platoon had been killed during a war in Iraq, the Associated Press reports

Gallego’s book, They Called Us “Lucky”: The Life and Afterlife of the Iraq War’s Hardest Affected Unitco-written with Jim DeFelice and published last year by William Morrow, claimed that: Washington Post journalist Ellen Knickmeyer reported the loss of Gallego’s Lima Comopany platoon, which shocked members of the soldiers’ families.

But Knickmeyer never made that claim. She correctly reported that four members of the platoon were killed in an explosion, although her report was apparently misinterpreted by some readers, including friends and family of soldiers.

William Morrow said on Twitter that the passage in Gallego’s memoir would be corrected. The amended passage admits that Knickmeyer’s report was correct.

A Gallego spokesperson told the AP that the Arizona Democrat would not apologize to Knickmeyer, saying that “apologizing for his emotional reaction and trauma, and recounting it in his book, is not appropriate.”

However, his co-author, DeFelice, expressed regret for the mistake on Twitter, to write“I apologize for the inconvenience caused by the original version. It was a traumatic event and I can only feel deep sadness and sympathy for everyone.”
