'Where does this stop?' Angry Obama eviscerates Trump in fiercest rebuke yet

President Barack Obama on Tuesday went after Donald Trump and fellow Republicans in his sharpest rebuke yet of some of the policies floated by the presumptive GOP nominee.

Obama spoke after a meeting with his national-security council, addressing the nation in the aftermath of the Orlando massacre - the deadliest mass shooting in US history. ISIS has claimed responsibility for the shooting, which was carried out by a 29-year-old man who officials have said became radicalized.

Although he did not mention Trump by name in the speech, Obama took several shots directed at the "presumptive Republican nominee."

The president lambasted Republicans for insisting he use the phrase "radical Islam."

"That's the key, they say," Obama said. "We can't defeat them unless we call them radical Islamists. What exactly would using this label accomplish. What exactly would it change?"

"Would it make ISIL less committed to try and kill Americans? Would it bring in more allies? Is there a military strategy that is served by this? The answer is none of the above," he continued.

He labeled the constant insistence on using the term, which has been repeatedly pushed by Trump, a "political distraction." Obama added that he's been clear about how extremist organizations have "perverted" Islam.

Counterterrorism experts have never said, "Man, if we really used that phrase, we're really going to turn this thing around," Obama said, sarcastically

"If there's anyone out there who thinks we're confused about who our enemies are, that would come as a surprise to the thousands of terrorists we've taken off the battlefield," he continued, taking a dig at Trump's remarks from Monday, when the Manhattan businessman suggested Obama might have sympathy toward jihadists.

Obama continued aiming at Trump, saying the implication that the government isn't taking the fight against terrorism seriously would come as "a surprise" to the thousands of people, including military personnel, who are putting their lives at risk to combat terror groups such as ISIS.

He added that it was also insulting toward intelligence and law-enforcement officials who work to defeat plots in order to keep citizens safe.

"Including politicians who tweet," the president said. "And appear on cable news shows."

He called the insistence on using the term "radical Islam" a "political talking point" and "not a strategy."

"It has nothing to do with political correctness, and it has everything to do with defeating extremism," he said of why he doesn't use the phrase, adding that connecting all of Islam with terrorism is what organizations such as ISIS want.

Obama shifted over to some of Trump's policy points, and tore into his proposal to indefinitely bar all Muslims from entering the United States.

"Where does this stop?" Obama said, adding that Muslim attackers in the Ft. Hood, San Bernardino, and Orlando shootings were born in America.

"They were all US citizens," Obama said. "Are we going to start treating all Muslim Americans differently? Are we going to start subjecting them to special surveillance?"

"Do Republican officials actually agree with this?" he continued. "Because that's not the America we want."
