Hillary Clinton Selects Tim Kaine, a Popular Senator From a Swing State, as Running Mate

Hillary Clinton named Senator Tim Kaine of Virginia to be her running mate Friday, selecting a battleground-state politician with working-class roots and a fluency in Spanish, traits that she believes can bolster her chances to defeat Donald J. Trump in November.

Mrs. Clinton’s choice, which she announced via text message to supporters, came after her advisers spent months poring over potential vice-presidential candidates who could lift the Democratic ticket in an unpredictable race against Mr. Trump.
