The third Republican debate is over in Colorado. Here are some highlights from the AP.
Rubio defends his job in the Senate
Florida Sen. Marco Rubio is defending his job performance against criticism from one of his constituents — Jeb Bush.
Bush is joining critics who say Rubio has skipped too many votes in the Senate as he campaigns for president.
Bush says Rubio should do his job. He says "this was a 6-year term and you should be showing up to work."
Bush adds that if Rubio didn't want to show up for votes, he should "just resign and let someone else take the job."
The attack was the harshest of the debate so far and was Bush's first chance to stand out on the crowded stage.
Rubio is pushing back hard. He says media criticism of his voting record is an example of bias against conservatives. And Bush is only piling on because "we're running for the same position and someone has convinced you that attacking me will help you."
Bush goes after Rubio
Former Florida Gov. Jeb Bush is attacking Marco Rubio for missing Senate votes.
Critics have gone after Rubio for missing a lot of votes during his first term in Congress. Bush took it a step further in the Republican Party's debate Wednesday night.
Bush told Rubio he signed up for a six-year term and "should be showing up for work."
Carson goes after income tax loopholes
Retired neurosurgeon Ben Carson says he would get rid of all income tax deductions and loopholes if he were president.
Carson says during the third Republican presidential debate that there also needs to be strategic cutting. He says anyone who believes savings couldn't be found in federal agencies is living in a "fantasy world."
Carson says his tax plan would result in a flat tax around 15 percent.
Gov. Kasich comes out swinging against outsiders
Ohio Governor John Kasich says economic proposals from his rivals for the Republican presidential nomination are "just fantasy."
He slammed proposals from neurosurgeon Ben Carson and developer Donald Trump as unrealistic and deficit-busting. Kasich has proposed a large tax cut as well and promised to balance the budget through unspecified cuts.
Trump quips that Kasich's poll numbers are so bad he barely qualified for the debate.
Former technology executive Carly Fiorina says it is the "height of hypocrisy" for Hillary Rodham Clinton to talk about being the first woman president when "every single policy" she endorses is "demonstrably bad for women."
Fiorinia is joining Texas Sen. Ted Cruz in going after Clinton in the third Republican presidential debate.
Fiorina says 92 percent of the jobs lost during President Barack Obama's first term belonged to women. And Cruz says 3.7 million women went into poverty during Obama's presidency.
Cruz says big government benefits the wealthy, lobbyists and giant corporations. He says he is fighting for Hispanics, women and single mothers.
Kasich touts resume
Ohio Gov. John Kasich isn't going to let voters forget he helped lead efforts to balance the federal budget while serving in Congress in the 1990s.
He calls the budget deal passed by the House on Wednesday a "silly deal" that is more of "the same old stuff." If elected president, he says he'd push for a balanced budget amendment to make sure the government doesn't spend more than what is has.
Kasich says his time in Congress and two terms as Ohio's governor serve as proof of his ability to manage a growing economy and write responsible budgets. He brings up his time working on the balanced budget in Congress often on the debate stage and on the campaign trail.
Rubio uses personal story to his advantage
Marco Rubio is dismissing questions about whether his history of personal financial woes disqualifies him from being in charge of the federal government.
A bank once moved to foreclose one of Rubio's homes. He couldn't account for thousands of expenses from political committees he ran. Last year he sold retirement funds to pay bills despite earning millions over the past decade.
Rubio dismisses those problems as discredited attacks from Democrats.
He says his struggles to provide for his four children are the reason he is pushing a tax plan that would help families. He also recounts his humble upbringing as the son of immigrant parents who worked as a bartender and a housekeeper.
Christie backs "political justice department"
Chris Christie says the Justice Department under President Obama has been a "political Justice Department."
Christie says the department has let politics drive prosecutions and given some favored companies "a pass" while coming down unnecessarily hard on others.
The New Jersey governor and former prosecutor made the assertion when asked whether he thought some General Motors executives should go jail for their role in a deadly ignition-switch defect scandal.
Christie says they should and adds, "If I were a prosecutor that's exactly where'd they be."
Christie is also criticizing the department's decision to prosecute CIA chief David Petraeus for sharing classified information.
Carson slams regulation
Ben Carson says regulation is choking small businesses in America.
Asked about drug prices, Carson focused his answer on business oversight. He says job creation is limited because businesses are dealing with excessive regulations.
Carson says that instead of focusing on one specific group, the country needs a "major reduction" in "regulatory influence."
Rand Paul says he's not worried about government shutdown
Kentucky Sen. Rand Paul says he's more worried about Congress bankrupting the American people than he is about a government shutdown.
Paul says he opposes the budget deal passed Wednesday evening in the House of Representatives, which raises the county's borrowing limit as well as spending caps.
He says Democrats and Republicans backing the deal are part of an "unholy alliance" to spend the country "into oblivion."
Paul says the deal gives him little hope that Wisconsin Rep. Paul Ryan, likely to be the next House speaker, will bring meaningful change.
Cruz goes after media
Texas Sen. Ted Cruz has a beef with the media.
Cruz says the questions being asked him and other Republican candidates in the third debate are unfair.
He says they "illustrate why the American people don't trust the media. This is not a cage match."
He says the CBNC moderators are more interested in pitting the candidates against one another rather than "talking about the substantive issues people care about."
Cruz says the Republican debate is a stark contrast with the Democratic contest, "where every fawning question" was about "which one of you is more handsome and wise?"
His response came to a question about whether his opposition to a budget deal in Congress shows that he's not a problem-solver.
Fiorina defends business career
Carly Fiorina says her record as former CEO of Hewlett-Packard isn't a liability, but proof of her leadership skills.
During the third Republican debate, Fiorina was asked about her time at the helm of HP, where she laid off 30,000 workers and was fired by the board.
Fiorina says she was brought in to be a change agent and had to make some "tough calls." She also touts the fact that former HP board member Tom Perkins has recently spoken up on her behalf.
Fiorina says she is prepared to "run on my record all day long."
Trump not too happy with CNBC
Donald Trump sounds like he'd like to fire CNBC debate moderator John Harwood.
Harwood's first question to the real estate mogul suggested Trump's promises were so huge they were cartoonish. Harwood asked Trump if he was running a "comic book version of a presidential campaign."
Trump rejected the phrase and added, "it's not a very nicely asked question."
Trump says his proposals are realistic. He says if China can build a 13,000-mile Great Wall, he can build a wall along 1,000 miles of the U.S.-Mexican border.
Trump also says he can force Mexico to pay for the wall. He says "a politician cannot get them to pay, I can."
Cruz says he's too 'agreeable'
Texas Sen. Ted Cruz says his biggest weakness is that he's "too agreeable." He's kidding.
The notably fiery Cruz, who often stands against his own party in Congress, says his biggest weakness is actually that he's a fighter who is passionate about the Constitution.
He says he doesn't care if he's not the guy voters want to have a beer with, because he's the one who will make sure they get home.
Christie goes after Democrats
Chris Christie is wasting no time in lashing out at Democrats.
The New Jersey governor is using an opening question about his greatest weakness to clobber the three Democratic candidates for president.
Christie lists the GOP's possible opponents as "the socialist," ''the isolationist" and "the pessimist."
Vermont Senator Bernie Sanders is a self-declared socialist. It's not clear who is the isolationist but Christie says Hillary Clinton is the pessimist.
Christie promises "you put me on the stage with her next September and she won't get within 10 miles of the White House."
