On his first day, Trump begins to set up his administration

WASHINGTON (AP) — President Donald Trump quickly assumed the mantle of the White House and began setting up his new administration on Friday, signing a bill that allows retired Gen. James Mattis to serve as his defense secretary, as well as the nomination papers for his other Cabinet choices.
Less than an hour after delivering a stinging rebuke of the political status quo in his inaugural address, Trump sat in an ornate room steps from the Senate floor to officially assemble his core team.
