1. President-elect Donald Trump has chosen three hawkish loyalists for key posts.

They are Senator Jeff Sessions as attorney general, Representative Mike Pompeo as C.I.A. director and retired Lt. Gen. Michael Flynn as national security adviser.

All three are regarded as outliers from conventional Republican thinking, shunned in various ways for viewpoints that were seen as unacceptable or overly partisan.

Mr. Sessions, an Alabama conservative, was denied a federal judgeship by the Senate Judiciary Committee in 1986 because of racially charged comments.
