Republicans are demanding answers from the Department of Defense after learning about Defense Secretary Lloyd Austin's hospitalization that was kept hidden for days. 

GOP lawmakers are calling on Austin to testify or even be ousted from his position over reports that the Pentagon waited several days to inform top officials that the Biden staffer was in the hospital. 

Late Friday, the Pentagon announced that Austin had been admitted to Walter Reed National Military Medical Center beginning Monday and finally returning to his duties on Friday. According to reports, the White House was unaware of Austin's condition. 

Ranking member of the Senate Armed Services Committee, Sen. Roger Wicker (R-MS), called the lack of transparency from the department "unacceptable." 

"We are learning more every hour about the Department's shocking defiance of the law. When one of the country's two National Command Authorities is unable to perform their duties, military families, Members of Congress, and the American public deserve to know the full extent of the circumstances. This episode further erodes trust in the Biden Administration, which has repeatedly failed to inform the public in a timely fashion about critical events such as the Chinese spy balloon and the withdrawal from Afghanistan," Wicker said.
