Marco RubioMarco Antonio RubioRubio: Kaepernick deserves to be in the NFL Congress — when considering women’s health, don’t forget about lung cancer Anti-Maduro Venezuelans not unlike anti-Castro Cubans of yore MORE repudiated President Obama's push for gun control Thursday, warning that Americans who believe the president wants to take their guns are right.  

"I am convinced that if this president could confiscate every gun in America, he would. I am convinced that this president, if he could get rid of the Second Amendment, he would," he said during the sixth Republican presidential debate. 
"I’m convinced because I see how he works with his attorney general not to defend the Second Amendment but to figure out ways to undermine it."
Rubio added that neither the president's executive actions on gun control nor his push for stricter laws would have prevented the recent mass shootings in America. 
"Criminals don’t buy their guns from a gun show. ... ISIS and terrorists do not get their guns from a gun show," he said. 
"We are in a war against ISIS ... the last line standing between them and our families might be us and a gun. When I'm President of the United States, we are defending the Second Amendment, not undermining it the way Barack ObamaBarack Hussein ObamaHolder: DOJ, FBI should reject Trump's requests The Hill's 12:30 Report — Sponsored by Delta Air Lines — Frenzy over Kennedy retirement rumors | Trump challenges DOJ Asian American and Pacific Islander community will be critical to ensuring successful 2018 elections for Democrats MORE does."
When asked by moderator Neil Cavuto if he was overreacting by saying the president would take away everyone's guns, Rubio quoted Obama's infamous line that people in economically depressed regions often "cling to guns or religion" from his 2008 campaign.

"We don't need to add new rules, we need to make sure the FBI does its job," Bush said. He said the suspected shooter in last year's deadly attack on a South Carolina church would have failed a background check had it been done.
Then Chris Christie, who has been chided by Republicans for his own previous support of gun control policies, piled on, hitting the president for his recent executive actions.
"That's not a democracy, that's a dictatorship. ... This guy is a petulant child. That's what he is," he said.
"The American people have rejected your agenda, and now you are trying to go around it? That's not right, that's not constitutional, and we are going to kick your rear end out of the White House."
