The speculation began in earnest after The New York Times published a story detailing how Pence has engaged in more political activity than vice presidents typically do: He has has created his own political fundraising committee and has hosted Republican donors and activists at his residence at the Naval Observatory in Washington.
Pence advisers have also indicated to party donors that the vice president has plans to run if Trump does not, the Times reported.
Marc Lotter, a Pence spokesman, said the Times’ report was “wishful thinking.”
Speculation has also stirred as the Justice Department, led by special counsel Robert Mueller, has continued to probe allegations that the Trump campaign colluded with Russia during last year’s election. And Trump continues to face unfavorably approval ratings: According to HuffPost Pollster, which aggregates publicly available polling data, 58.6 percent of Americans say they disapprove of Trump’s job performance, while 37.3 percent approve.
