President-elect Donald Trump has filled key posts for his second term in office, prioritizing loyalty to him after he felt bruised and hampered by internal squabbles during his first term. Among his choices are Robert F. Kennedy Jr., as health secretary, Florida Sen. Marco Rubio as secretary of state and TV talk show host Dr. Mehmet Oz to oversee the Medicare and Medicaid programs. Former Florida Rep. Matt Gaetz was Trump's first choice for attorney general, but Gaetz ultimately withdrew his name following scrutiny over a federal sex trafficking investigation he was embroiled in.
