Carly Fiorina proposed to go to zero-based budgeting for the federal government, which would force it to justify all spending and expenses made for each new fiscal period.
9:57 p.m. Chris Christie doesn't want the government involved in regulating activities like fantasy football leagues.
He became visibly frustrated when candidates were posed the question of whether daily fantasy sports should be considered gambling. Listing off threats like extremist terror groups ISIS and al-Qaeda, Christie said that the government should prioritize those concerns before anything else.
"Enough on fantasy football -- who cares!" he said.
Responding to a question about what the U.S. can do on climate change, Christie said the answer is not to tax oil and gas companies.
Rather, the New Jersey governor touted what his own state did to promote alternative energy sources: "We worked with the private sector" on solar energy, Christie said.
9:46 p.m. On the gun control debate, Trump said that "yes, I might feel more comfortable" if his employees carried guns to their workplace.
"I like to be unpredictable," Trump added. He pointed out that he has a concealed carry permit in the state of New York, which he said "is very unusual" in the state.
The real estate mogul also slammed gun-free zones, like the one at Oregon's Umpqua Community College, saying they're "target practice for the mentally ill, the sickos."
He added that he would change the policies on Trump properties that don't allow guns.
9:38 p.m. Ohio Gov. John Kasich, whose state will vote on ballot initiative that would legalize medical and recreational marijuana use, called drug use "one of the greatest scourges of this country."
9:31 p.m. Former Arkansas Gov. Mike Huckabee compared the star of Wednesday's news cycle, a military blimp that broke loose from its tether in Maryland, to the federal government.
"If you saw that blimp that got cut loose in Maryland today, that's a perfect example of government," Huckabee said. "I mean what we had was something the government made, basically a bag of gas that cut loose, destroyed everything in its path, left thousands of people powerless. But they couldn't get rid of it because we had too much money invested in it, so we had to keep it. That is our government today.
9:30 p.m. Candidates promote their tax plans as good for the middle class.
Florida Sen. Marco Rubio said that his tax proposal is "the most pro-growth tax plan" of the GOP field, and that for the lower- and middle-income brackets, the "greatest gains percentage-wise will be at the lower end of our plan."
Kentucky Sen. Rand Paul proposes to get rid of the payroll tax, in addition to cutting income taxes, which he said would "spread the tax cut to all socio-economic" brackets.
9:24 p.m.Trump pushes back against CNBC moderators that say the businessman had criticized Facebook's Mark Zuckerberg for the tech entrepreneur's immigration proposals.
"I was not at all critical of" the Facebook co-founder, Trump said.

Carson says that "the constitution protects everyone," despite his belief that "marriage is between one man and one woman."
9:08 p.m. When questioned on his own troubled personal finances, Florida Sen. Marco Rubio dismissed the concerns as a "litany of discredited attacks" from Democrats.

9:03 p.m. "It's a political Justice Department," Christie said, slamming President Obama's administration.
8:51 p.m. Chris Christie promises to save a trillion dollars with his entitlement reform platform over the next ten years. He adds that the government hasn't kept senior citizens informed about social security funds.
"The only way we're going to keep our promises to seniors," Christie said, was to "tell the truth."
8:48 p.m. Rand Paul defended his plans to filibuster the recently negotiated budget deal, saying budget negotiations "should be leveraged to try and reform government." He added that he doesn't believe that "there will be much change" in the House of Representatives, even with a new leader like Rep. Paul Ryan, R-Wisconsin.
8:40 p.m. Carly Fiorina defended her record at Hewlett-Packard, where she was fired after the company took a nose dive.
"I was recruited to HP to save a company," Fiorina said. "As an outsider, I cut the bureaucracy down to size... we saved 80,000 jobs... I had to make some tough calls in some tough times."
She mentioned that the board member who held her accountable and voted for her firing at the company, Tom Perkins, actually came out and endorsed her run for the presidency.
8:35 p.m. Sen. Marco Rubio was asked about a recent editorial from Florida newspaper, the Sun-Sentinel, calling for his resignation from the 2016 race. Rubio pointed to his record in the Senate to say that he has done his job and that the Sun-Sentinel was guilty of liberal bias.
"This is another example of the double standard that exists in this country between the mainstream media and the conservative movement," Rubio said.
Former Florida Gov. Jeb Bush jumped in to criticize Rubio for leaving his Senate seat before his six-year commitment to Floridians was up.
"He got endorsed by the Sun Sentinel because he was the most talented guy in the field," Bush said. "He is a gifted politician. But Marco when you signed up for this, this was a 6 year term and you should be showing up to work."
Rubio didn't seem willing to engage in a fight with his former mentor, saying instead, ""I'm not running against governor bush... I'm running for president."
8:27 p.m. When Ben Carson was pressed by CNBC moderators on his tax plan being unrealistic and would eventually put the U.S. economy into a trillion-dollar debt spiral, the retired neurosurgeon says that "when we put the facts down, you'll see that it's not true."
Kasich interrupted to say that tax plans like Carson's and Trump's "were a fantasy."
"These plans would put us in trillions and trillions of dollars in debt," the Ohio governor said. "We cannot elect somebody that does not know how to do the job."
In response, Trump attacked Kasich's own record, saying the governor "got lucky with a thing called fracking" in Ohio, referring to the state's booming energy industry. The billionaire also attacked Kasich's record as a banker for Lehman Brothers.
Texas Sen. Ted Cruz weighed in on the tax code debate and said he would institute a simple flat tax of ten percent, with a business flat tax of 16 percent.
Carly Fiorina added that in order to simplify the tax code, she would restrict its length to just three pages.
8:24 p.m. The first question was directed at Donald Trump: Does the billionaire businessman believe the race reads like a comic book?
