President Joe Biden acknowledged that Defense Secretary Lloyd Austin's failure to inform him about his hospitalization for complications from prostate cancer surgery was a lapse in judgment. Despite the criticism and calls for resignation, Biden expressed confidence in Austin's leadership. Austin, 70, underwent surgery on Dec 22, developed an infection on Jan 1, and was admitted to intensive care. Biden and administration officials were informed on Jan 4, and Austin revealed his cancer diagnosis on Tuesday, prompting scrutiny from both political parties.
