Republican debaters attack Marco Rubio as inexperienced, Ted Cruz as unethical
7 White House hopefuls to take the stage in New Hampshire days before high-stakes primary
Marco Rubio, a first-term senator on the rise in the U.S. presidential race, faced a barrage of attacks in Saturday night's Republican debate, with rivals vigorously challenging his readiness to be president and the depth of his expertise as they sought to salvage their own White House hopes.
Senator Ted Cruz, fresh off his victory in the Iowa caucuses, also came under withering criticism for controversial political tactics, with one candidate disparaging him for having "Washington ethics" and being willing to test the campaign's legal limits.
The focus on the two senators allowed Republican frontrunner Donald Trump to go largely untouched in his return to the debate stage. His grip on the Republican lead has been shaken by his second-place finish in Iowa, though the next contest Tuesday in New Hampshire is still his to lose.

In the race for the Democratic presidential nomination, former Secretary of State Hillary Clinton is facing a strong challenge from liberal Senator Bernie Sanders.
New Hampshire's primary could further winnow an already shrinking Republican field. Hard-fought, expensive and far-ranging, the campaign has become a fight for the future of the Republican Party, though the direction it will ultimately take remains deeply uncertain.
Florida's Senator Rubio has sought to appeal both to mainstream Republicans and those eager to upend the status quo. But his rivals, particularly New Jersey Gov. Chris Christie, have been blistering in their criticism of what they see as his slim qualifications to serve as commander in chief.
"You have not been involved in a consequential decision where you had to be held accountable," Christie said. "You just simply haven't."
Last chance for Christie, Bush, Kasich?
Christie, as well as former Florida Gov. Jeb Bush and Ohio Gov. John Kasich, has staked his campaign on New Hampshire, pouring most of his resources into the state in recent weeks. All three played a more substantial role in this debate than in earlier contests, though each is still likely to face intense pressure to end his campaigns if he's unable to pull off a strong finish in New Hampshire.
"That's what Washington, D.C., does," Christie said. "The drive-by shot at the beginning with incorrect and incomplete information and then the memorized 25-second speech that is exactly what his advisers gave him."
Rubio has sought to deflect criticism of his relative inexperience and the comparisons it draws to President Barack Obama by arguing the problem with the president isn't that he's naive, but that he's pushing an ideology that hurts the country. He made that point repeatedly throughout the debate.
Rubio wavered in defending his decision to walk away from the sweeping immigration bill he originally backed in the Senate — perhaps the legislation he's most closely associated with — and said he wouldn't pursue similar legislation as president.
"We can't get that legislation passed," Rubio said of the bill that would have provided a pathway to citizenship for millions of people in the United States illegally. The senator found his footing later in the debate when outlining his call for more aggressive action to fight the Islamic State in Iraq and Syria and emphasizing his anti-abortion stance.
Cruz apologizes for his campaign's actions
Cruz apologized for his campaign's actions Saturday, but not before Carson jabbed him for having "Washington ethics."
Those ethics, he said, "say if it's legal, you do what you do to win."
Trump was back on the debate stage after skipping the last contest before the Iowa caucuses. After spending the past several days disputing his second-place finish in Iowa, he sought to refocus on the core messages of his campaign, including blocking Muslims from coming to the U.S. and deporting all people in the country illegally, all while maintaining his has the temperament to serve as president.
"When I came out, I hit immigration, I hit it very hard," Trump said. "Everybody said, 'Oh, the temperament,' because I talked about illegal immigration."
