Tonight, President Biden taking a much different strategy, urging the former president to put Border Security above politics to help solve the problem now. Instead of telling members of congress to block this legislation, join me or ill join you in telling the congress to pass this bipartisan Border Security bill.

Defense secretary lloyd austin was grilled today about why he kept his hospital visit a secret, even from the president. Heres Martha Raddatz.

I did not handle it right. As you know, i have apologized, including directly to the president. And i take full responsibility. Reporter austin insisting there was no lapse in the chain of command, given that his deputy took control, but republican lawmakers showed austin no mercy. Someone needs to be held accountable. Reporter Congressman Jim Banks calling it an embarrassment. Either the president is that aloof or you are irrelevant. Which one is it, mr. Secretary . Its neither. That the president would go three days without knowing that his Secretary Of Defense is not on the job . Its neither. The president is not aloof. Reporter austin said he never told staff his absence was because of a scheduled surgery or that he was later rushed back by ambulance because of complications. When did your staff find out you were at the hospital . I dont know when you dont know when you told your staff that you were at the hospital . Are you kidding me . Reporter but democrats defended austin, arguing congresss focus needs to be passing a stalled Military Aid Package for ukraine. I would challenge any member on the other side of this aisle to claim that the Secretary Of Defense not fully informing the president for three days is somehow more important than walking away from that obligation that we have made and that the whole world is watching us on. Reporter as for notifying the white house, Secretary Austin said he never asked anyone to lie, and a Pentagon Review found no ill intent by austin or his staff for the failure to inform. But the pentagon, david, is making changes in how to handle notifications. David . David Martha Raddatz in washington. Thanks, martha.
