Republican presidential candidates squared-off over an array of foreign and domestic policy issues late Thursday, as they met in Detroit for the party's 11th debate of the election season.
SPRINGFIELD ‒ Republican presidential candidates squared-off over an array of foreign and domestic policy issues late Thursday, as they met in Detroit for the party's 11th debate of the election season.
The prime time event, hosted by Fox News from Detroit's Fox Theater, offered the four participating GOP White House hopefuls another chance to garner support for their respective presidential campaigns ahead of upcoming primaries in Michigan, Florida and Ohio.
With Donald Trump winning several states on Super Tuesday earlier this week, the three lower polling candidates went after the businessman personally and on his policies throughout the debate.
The event, moderated by Fox News' Bret Baier, Megyn Kelly and Chris Wallace, came shortly after 2012 GOP presidential nominee Mitt Romney urged the GOP to nominate anyone but the businessman.
Here are five takeaways from the prime time event:
Trump fired back at Romney, defended his policy proposals.
Responding to Romney's suggestion that Trump's "domestic policies would lead to recession," the businessman brushed off the former Massachusetts governor's criticism and echoed critiques he leveled against him in the last debate.
Calling the 2012 GOP nominee a "failed candidate," Trump argued that Romney should've easily beaten President Barack Obama and questioned the motive of his current attacks.
"He failed miserably and it was an embarrassment to everybody, including the Republican Party. It looked like he went away on a vacation the last month," he said. "Obviously he wants to be relevant, he wants to be back in the game."
Trump further defended his domestic and trade policies against Romney's criticism, pointing to money the U.S. is losing in its trade deals with various countries.
"I believe in free trade also, but if you look at China and if you look at Japan, if you look at Mexico, both at the border where they're killing us and with trade, and every other country we do business with, we are getting absolutely crushed on trade...We will make great trade deals," he contended.
Marco Rubio stood by his recent decision to attack Trump on the campaign trail.
Although the Florida senator acknowledged that he initially sought to not engage in personal attacks, he argued that if anyone deserved them it's his GOP rival.
Rubio argued that Trump has mocked several people in recent months, including candidate and others.
"This campaign for the last year Donald Trump has basically mocked everybody with personal attacks. He has done so to people that are sitting on the stage today. He has done so about people that are disabled. He has done it about every candidate in this race," he said. "So if there is anyone who has ever deserved to be attacked that way, it has been Donald Trump, for the way he has treated people in the campaign."
Rubio chastised the media for its coverage of those attacks, adding that he would instead like to focus on policy issues.
Trump, who said he would like to take back his comments calling Rubio "a lightweight," took issue with the senator's recent criticism regarding the size of his hands.
"Nobody has ever hit my hands. I have never heard of this. Look at those hands. Are they small hands?" he said. "And he referred to my hands, if they are small, something else must be small. I guarantee you there is no problem. I guarantee."
Kasich defended his path forward in seeking the Republican presidential nomination.
Despite failing to win one state so far this primary season, the Ohio governor rejected claims that his White House run won't see success.
Kasich argued that while the media wrote him off despite his second place finish in New Hampshire, he has placed well and won delegates in a handful of states.
"I split delegates in Vermont with Donald Trump, I finished second in Massachusetts, and we won delegates in Virginia. But, guess what? It's now March Madness and we're heading up North to the place -- to my turf, Okay?" he said. "And, let me just tell you this, I will win Ohio, and I am going to move all across this country, and over time as people begin to finally hear my message."
Trump doubled-down on his support of waterboarding and targeting terrorists' families.
Despite pushback his proposals have received from some military leaders, Trump stood by his support of targeting terrorists' families and using waterboarding to combat terrorism.
He added that military leaders would not refuse orders under his command.
"We should go for waterboarding and we should go tougher than waterboarding," the businessman said. "And, I'm a leader, I've always been a leader, I never had any problem leading people. If I say do it, they're gonna do it. That's what leadership is all about."
Rubio criticized Trump's foreign policy stance and questioned the seriousness of his proposals.
"This is a time for seriousness on these issues," he said.
Candidates stood by their pledge to support whomever becomes the party's nominee.
Despite efforts to undermine Trump winning the GOP nomination, all candidates pledged to support whomever is selected as the Republican Party's presidential nominee this summer.
Rubio, who spent much of the debate attacking Trump, said he would back the businessman if he goes on to represent the party in the general election because the GOP needs to stop the Democrats from winning the White House.
U.S. Sen. Ted Cruz, R-Texas, who joined Rubio in taking jabs at the businessman, meanwhile, said he would support Trump because he previously pledged to do so.
"I gave my word that I would," he said, adding that he has made it his mission to stay true to his promises in the U.S. Senate.
Kasich also said he would support Trump as the nominee out of respect for the party and the race.
"When you're in the arena you enter a special circle and you want to respect the people that you're in the arena with," he said. "So if he ends up as the nominee, sometimes he makes it a little bit hard, but I will support whomever is the Republican nominee for president."
Trump, who has hinted at waging a third party run, meanwhile, said he would support the GOP nominee, as well, adding that he is proud to have helped bring more people into the Republican Party.
