NEW YORK (AP) -- Donald Trump introduced Indiana Gov. Mike Pence as his running mate on Saturday, calling him "my partner in this campaign" and his first choice to join him on the Republican presidential ticket.
In their first joint appearance, Trump tried to draw a sharp contrast between Pence, a soft-spoken conservative, and Hillary Clinton, the Democratic presidential candidate. In fact, he spent more time lambasting Clinton than praising Pence, declaring she had led President Barack Obama "down a horrible path" abroad.
He said Pence would stand up to America's enemies and that he and the governor represent "the law-and-order candidates" at home.
"What a difference between crooked Hillary Clinton and Mike Pence," Trump said. He added: "He's a solid, solid person."
The joint appearance at a midtown Manhattan hotel was choreographed to try to catapult the party toward a successful and unified Republican National Convention, which kicks off in Cleveland on Monday. Republican officials were overwhelmingly positive in their reaction to Trump's selection of Pence.
Trump conceded that one of the reasons he'd selected Trump was to promote unity within the Republican Party.
"So many people have said `party unity,' because I'm an outsider," Trump said. "I don't want to be an outsider."
Pence, whose calm demeanor forms a marked counterpoint to the fiery Trump, was chosen in part to ease concerns in some GOP corners about the billionaire's impulsive style and lack of political experience. A steady conservative with extensive governing experience, Pence may also serve to reassure Republicans who are skeptical about Trump's conservative bona fides.
The Indiana governor is well-regarded by evangelical Christians, particularly after signing a law that critics said would allow businesses to deny service to gay people for religious reasons. But his hardline ideology is also at odds with Trump, who has largely avoided wading into social issues.
The Trump-Pence event offered Americans the first glimpse at what the 2016 Republican presidential ticket will look like, barring the unexpected. Just as Trump was settling on Pence, Republicans gathering in Cleveland essentially quelled the movement to oust Trump at the convention, all but assuring he'll be the GOP nominee.
"They got crushed," Trump said. "And they got crushed immediately, because people want what we're saying to happen."
Clinton's team was already painting Pence's conservative social viewpoints as out of step with the mainstream. Her campaign also seized on Trump's chaotic process for selecting and announcing his pick, painting Trump in a web video released Saturday as "Always divisive. Not so decisive."
Trump's formal announcement capped a frenzied few days in the presidential campaign, as early reports that Trump has settled on Pence threw speculation into overdrive. After days of his aides saying he hadn't made a final decision, the billionaire called Pence Thursday afternoon to offer him the job, but hours later postponed their first appearance after a truck attack killed 84 people in Nice, France.
Trump had spent weeks vetting vice presidential contenders, including former House Speaker Newt Gingrich and New Jersey Gov. Chris Christie, and only zeroed in on Pence in recent days. Pence, meanwhile, had faced a Friday deadline to withdraw from his re-election race for governor so he could run for vice president; his aides filed the paperwork about an hour before the cutoff.
In choosing Pence, Trump appeared to be looking past their numerous policy differences.
The Indiana governor has been a longtime advocate of trade deals such as NAFTA and the Trans-Pacific Partnership, both aggressively opposed by Trump. He's been critical of Trump's proposed temporary ban on foreign Muslims entering the U.S., calling the idea "offensive and unconstitutional." Pence also endorsed Sen. Ted Cruz instead of Trump ahead of Indiana's presidential primary.
