Austin Faces Questions About His Hospitalization From House Committee

Defense Secretary Lloyd J. Austin III presented himself before a congressional committee for chastisement on Thursday, continuing a round of mea culpas over his failure last month to tell his boss that he was in the hospital with complications from prostate cancer surgery.

Republican lawmakers had been preparing to lay into Mr. Austin before the hearing, calling former Defense Department officials for advice. Even the formal title of the hearing, listed on the House Armed Services Committee’s website, struck an ominous tone: “A Review of Defense Secretary Austin’s Unannounced Absence.”

Mr. Austin sought to get ahead of the expected scolding by apologizing — again — for keeping his hospitalization at Walter Reed National Military Medical Center a secret.

“We did have a breakdown in notifications during my January stay at Walter Reed — that is, sharing my location and why I was there,” he told the packed hearing room. “And back in December, I should have promptly informed the president, my team, and Congress and the American people of my cancer diagnosis and subsequent treatment.”

He added: “I take full responsibility.”

On Monday, the Pentagon released an unclassified version of a review of how Defense Department officials, including Mr. Austin, handled his hospitalization. The document offered little if any criticism and faulted no one for the failure to disclose his illness.

Even before the hearing began, lawmakers had been steaming. Representative Mike D. Rogers, Republican of Alabama and the chairman of the Armed Services Committee, resorted to capital letters to make his point on social media that “the review of Sec Austin’s actions, conducted by his own subordinates & subject to his approval, HELD NO ONE ACCOUNTABLE.”
