Washington — President-elect Donald Trump is expected to nominate Robert F. Kennedy Jr. to lead the Department of Health and Human Services, according to three sources familiar with the selection. Kennedy has a long record of criticizing vaccines, including spreading misleading claims about their safety.

The nomination of Rubio, a China hawk who's been sanctioned by Beijing, comes at a tense moment in the Indo-Pacific region.

The choices continued a pattern of Trump stocking his Cabinet with those he believes he can trust to execute his agenda rather than longtime officials with experience in their fields.
