(CNN) -- The Senate on Tuesday unanimously confirmed Robert McDonald, a former corporate CEO and an ex-Army officer, as the next Veterans Affairs secretary.
He replaces Eric Shinseki, who resigned in May amid an unfolding scandal at VA medical facilities.
McDonald takes over a massive bureaucracy with more than 300,000 full-time employees still reeling from allegations of delayed care and alarming mismanagement at major medical facilities.
Investigations continue and Congress appears ready to approve legislation this week authorizing new money and other steps to address cultural and managerial shortcomings at the Veterans Affairs Department.
McDonald also has promised to take "immediate actions" in his first 90 days to reform the troubled agency.
