Christie, Fiorina drop out of GOP presidential race(Read article summary)
Their departures leave seven men remaining from an original 17-person Republican field.
New Jersey Gov. Chris Christie and former business executive Carly Fiorina are ending their campaigns for the 2016 Republican nomination, narrowing the field of rivals facing businessman Donald Trump for the right to compete in the Nov. 8 presidential election.
A senior aide confirmed to Reuters on Wednesday that Christie would pull out, a day after the combative Republican's sixth-place finish in the New Hampshire primary raised doubts about his viability as a candidate.
Fiorina, a former Hewlett-Packard chief executive, said in a Facebook post on Wednesday she would suspend her campaign. The only woman in the Republican field placed seventh in New Hampshire.
Trump's remaining opponents, most of them mainstream Republicans, will likely benefit from their departures, which leave seven Republicans from a field that once had 17 candidates.
Christie had poured much of his campaign's resources into New Hampshire and had considered a good showing there critical. He won only about 7 percent of votes on Tuesday, despite a pugnacious performance at a Republican debate last weekend.
Trump, a billionaire real estate mogul and former reality TV star, has dominated the Republican race and easily won the party primary in New Hampshire on Tuesday on a wave of voter anger at traditional US politicians.
Sen. Bernie Sanders of Vermont, a democratic socialist, defeated former Secretary of State Hillary Clinton in the state's Democratic contest.
The results testified to the sizable share of American voters upset over the slow economic recovery, immigration and America's place in the world and who are willing to shake up Washington.
Trump's victory showed pundits were wrong to think he would quickly self-destruct based on his penchant for insults and imprecise plans for the presidency. He had lost last week to Sen. Ted Cruz of Texas in the first nominating contest, the Iowa caucuses.
Trump's remaining rivals are still splintered.
Ohio's Republican governor, John Kasich, finished second in New Hampshire, followed by Cruz, former Florida Governor Jeb Bush and Sen. Marco Rubio of Florida.
