Lloyd Austin called to testify before Congress on hospitalization

Why it matters: The initial secrecy surrounding Austin's two-week hospitalization following complications from prostate cancer treatment drew criticism from Congress members, and Biden called the decision a lapse in judgment.

Of note: Rogers wrote that when Austin last spoke with him he had "promised full transparency into questions regarding the secrecy" of his hospitalization, but he hadn't addressed all of the congressman's concerns.

• "I am alarmed you refused to answer whether you instructed your staff to not inform the President of the United States or anyone else of your hospitalization," Rogers said in his letter to Austin, who was released from the hospital on Monday.
• "Unfortunately, this leads me to believe that information is being withheld from Congress. Congress must understand what happened and who made decisions to prevent the disclosure of the whereabouts of a cabinet secretary," added Rogers, who asked for Austin to "promptly answer all outstanding questions" ahead of the hearing.

• Representatives for the Defense Department did not immediately respond to Axios' request for comment.
