New Jersey Governor Chris Christie is officially suspending his campaign for the Republican presidential nomination.

Christie posted on Facebook that he's leaving the race "without an ounce of regret."

A spokesperson said Christie broke the news in a meeting with his campaign staff this afternoon.

Earlier today, Carly Fiorina dropped out of the 2016 Republican presidential race.

The former technology executive announced on Twitter that she is suspending her campaign.

The 61-year-old drew positive reviews for several strong debate performances, in which she promoted her business expertise and argued that as the lone woman in the GOP field she was best positioned to oppose likely Democratic nominee Hillary Clinton. But she struggled to build support in a crowded primary field and her poll numbers lagged.

Fiorina struggled with criticism of her time at Hewlett-Packard, where she was ousted from the top job in 2005, after leading a major merger and laying off 30,000 people.  {Associated Press)
