Donald J. Trump’s campaign has signaled strongly to Republicans in Washington that he will pick Mike Pence, the governor of Indiana, as his running mate, though Republicans caution the party’s mercurial presidential candidate may still backtrack on his apparent choice.
Mr. Trump’s advisers have told national Republican officials that they are preparing to make an announcement with Mr. Pence, according to three people with knowledge of the conversations, who were not authorized to discuss them publicly. His campaign has said that it will unveil a running mate for Mr. Trump in New York on Friday.
Mr. Pence, a former congressman and radio host, emerged over the last week as the strong favorite of Mr. Trump’s political advisers and senior officials in the Republican Party.
But Mr. Trump himself has sent conflicting signals in recent days, as he has subjected his potential running mates to a final round of screening. He addressed a rally in Indianaalongside Mr. Pence on Tuesday night and met privately with him several times.
