President Biden of the United States announced on the 27th that Mr. Crane, who has served as the president's chief of staff, will retire, and Mr. Zientz, who has been in charge of measures against the new coronavirus, will be appointed as his successor.
Mr. Zientz, who is newly appointed as the president's chief of staff, has been promoting the spread of vaccines as a new coronavirus countermeasures coordinator since the beginning of the Biden administration, and the Obama administration has also played a major role in the introduction of a new medical insurance system. He was a person who played a role, and the American media reports that his high practical ability was highly evaluated.
Mr. Crane, who is retiring, said in a letter to President Biden that this month is the halfway point of the Biden administration's four-year term, saying, ``It's a good time to refresh the leadership. It's time for us to take on this role."
It's not uncommon for senior White House officials to change midway through a president's term, and the letter says Crane has served longer than eight of the last nine chiefs of staff.
