On July 14, it was reported that Mike Pence had been selected as Donald Trump's running mate, following his acceptance of Trump's offer. Trump had planned to officially announce his choice on July 15 at 11 am. ET, in Manhattan, but, following a terrorist attack in Promenade des Anglais, Nice, France, announced the day prior that he would postpone the announcement. On the morning of July 15, Trump announced via Twitter his choice of Indiana Governor Mike Pence as his vice presidential running mate. Trump made the formal announcement at a news conference at 11 a.m. on July 16. Pence had been running for re-election as Governor of Indiana, but Indiana law prevented him from appearing on the election ballot twice, so Pence suspended his gubernatorial campaign. Within the Trump campaign, Pence emerged as a potential running mate in May due to the backing of senior advisers Kellyanne Conway and Paul Manafort. CNN reported that multiple sources told them that Trump had second thoughts on the Pence pick and attempted to pick Christie instead, though the Trump campaign denied those reports. Following the selection, "The New York Times" noted that Pence is a "sturdy and predictable politician" who has a strong appeal to the Christian right. On July 19, the second night of the 2016 Republican National Convention, Pence won the vice presidential nomination by acclamation.
