Hillary Clinton on Dec. 15 night attributed her defeat to a convergence of two “unprecedented” events: the release of a letter by James B. Comey, the F.B.I. director, shortly before the election, and what she called an “attack against our country” by the Russian president, Vladimir V. Putin.
Mrs. Clinton has kept a low profile in the weeks since her defeat, mostly appearing on social media in photographs by passers-by who have spotted her walking her dogs near her home in Chappaqua, N.Y.
