Donald Trump said Sunday that in the wake of the mass shooting in Orlando, it's time for the United States to start looking at racial profiling as a preventative tactic. 
 
 "Well I think profiling is something that we're going to have to start thinking about as a country," the presumptive GOP nominee said in a phone interview with CBS' "Face the Nation. "Other countries do it, you look at Israel and you look at others, they do it and they do it successfully. And I hate the concept of profiling but we have to start using common sense and we have to use our heads." 
 
 "It's not the worst thing to do," he added. 
 
 Trump's comments come one week after 49 people were shot and killed in a gay nightclub in Orlando, the deadliest mass shooting in U.S. history. Following the massacre, Trump renewed his calls for a temporary ban on Muslims entering the U.S., saying it would have prevented the attack despite the fact that shooter Omar Mateen was born in the U.S.

 On Sunday, the GOP politician also said attacks like Orlando would stop if those in the Muslim community would "report" suspicious things. 
 
 "When you look at, when you look at people within the Muslim community and where people are living and they don't report, and a good example of that would be San Bernardino," he said. "I mean, they had bombs all over their apartment floor and people saw it and nobody reported them, and 14 people were killed, many injured." 
 
 Mateen, Trump added, had definite "red flags" before the attack. "You look at his past, I mean? I've never seen a past quite like that," he said of Mateen. "You look at his record in school, you look at a lot of other things. There were a lot of red flags, this was not a very good young man." 
 
 Trump said he's working with the National Rifle Association on the details of a policy that would ban people on the no-fly list from purchasing guns. 
 
 "We understand there are problems with that because some people are on the terror watch list that shouldn't be on," he said. "So I'm working with the NRA, we're discussing it and again the NRA has the best interests of our country, it just has the absolute best interests of our country." 
 
 Asked about GOP leaders' criticism of him in recent days, especially over his renewed focus on the Muslim ban, Trump said those Republicans should stop "talking so much" and just "do their job." The issue is compounded, he added, when the media focuses more on his detractors in the GOP than his supporters. 
 
 "I think that honestly they should go about their business and they should do a wonderful job and work on budgets and get the budgets down and get the military the kind of money they need and lots of other things, and they shouldn't be talking so much," he said. "They should go out and do their job, let me do my job." ||||| Republican presidential candidate Donald Trump, left, shouts to Secret Service agents that supporter Diana Brest, right, had been waiting in line since 2 a.m. to see the candidate speak at a rally Saturday,...

 WASHINGTON (AP) — Donald Trump says the country should "seriously" consider profiling Muslims in the United States as a terrorism-fighting tool. 
 
 The presumptive Republican presidential nominee says other countries use profiling and "it's not the worst thing to do." 
 
 In an interview with CBS' "Face the Nation," Trump said, "I hate the concept of profiling, but we have to start using common sense" and "look at it seriously." 
 
 Profiling is the government practice of targeting people for investigation based factors such as their race, religion or nationality. Civil libertarians have decried the practice as discriminatory. 
 
 Trump says that in the age of international terrorism, it's a matter of choosing "common sense" over "political correctness."

 Donald Trump seemed to repeatedly accuse President Obama on Monday of identifying with radicalized Muslims who have carried out terrorist attacks in the United States and being complicit in the mass shooting at a gay nightclub in Orlando over the weekend, the worst the country has ever seen. 
 
 "Look, we're led by a man that either is not tough, not smart, or he's got something else in mind," Trump said in a lengthy interview on Fox News early Monday morning. "And the something else in mind — you know, people can't believe it. People cannot, they cannot believe that President Obama is acting the way he acts and can't even mention the words 'radical Islamic terrorism.' There's something going on. It's inconceivable. There's something going on." 
 
 In that same interview, Trump was asked to explain why he called for Obama to resign in light of the shooting and he answered, in part: "He doesn't get it or he gets it better than anybody understands — it's one or the other, and either one is unacceptable."

 For months, Trump has slyly suggested that the president is not Christian and has questioned his compassion toward Muslims. Years ago, Trump was a major force in calls for the president to release his birth certificate and prove that he was born in the United States. On the campaign trail, Trump has repeatedly stated as fact conspiracy theories about the president, his rivals and Muslims, often refusing to back down from his assertions even when they are proven to be false. 
 
 During an appearance on the "Today" show later Monday morning, Savannah Guthrie pushed Trump to explain what he meant in the earlier interview. 
 
 "Well there are a lot of people that think maybe he doesn't want to get it," Trump said. "A lot of people think maybe he doesn't want to know about it. I happen to think that he just doesn't know what he's doing, but there are many people that think maybe he doesn't want to get it. He doesn't want to see what's really happening. And that could be."

 Guthrie asked Trump why that would be, and the presumptive Republican presidential nominee responded: "Because Savannah, Savannah, why isn't he addressing the issue? He's not addressing the issue. He's not calling it what it is. This is radical Islamic terrorism. This isn't fighting Germany; this isn't fighting Japan, where they wear uniforms." 
 
 Trump's spokeswoman and campaign manager have yet to respond to a request for a fuller explanation of Trump's comments about the president. 
 
 White House press secretary Josh Earnest said later Monday that he had not spoken with the president about Trump's criticisms, but he emphasized that "when you are focused on something as big as helping the country respond to the worst mass shooting in the nation's history, it's important not to get distracted by things that are so small." 
 
 Obama did not mention Trump during brief remarks to reporters in the Oval Office after meeting with his national security advisers Monday morning. 
 
 In December, Trump called for a temporary ban on allowing foreign Muslims into the country as a way to protect against terrorist attacks. Recently, as he faced pressure from fellow Republicans, Trump seemed to back away from the religion-based ban, saying that it was merely a suggestion. But after this weekend's mass shooting, Trump has doubled down on his call for a ban, saying that the United States is allowing in terrorists who could stage even worse attacks. 
 
 "That man yesterday was sick with hate," Trump said on Fox. "You have many, many people, thousands of people, already in our country that are sick with hate. And people that are around him, Muslims, know who they are, largely. They know who they are. They have to turn them in. They know who they are. They see them." 
 
 During a brief interview on ABC's "Good Morning America," Trump was asked how a ban on foreign Muslims could have prevented the Orlando shooting, as the shooter, identified as Omar Mateen, was born in the United States.

 "We have many people coming in whose hate is equal to his and just as bad and even worse, frankly, and we have to stop people from coming in," Trump said, adding that gun control measures also could not stop a terrorist attack. 
 
 "The problem was that we have a maniac, we have a madman. He could have used a bomb. He could have used other things, just as easily, just as easily," Trump said. "It would have been, probably, even more devastating. So that's not the problem." 
 
 Trump has repeatedly taken credit for having been "right" on issues of terror, and on Monday he continued to face scrutiny for a tweet he posted on Sunday that read: "Appreciate the congrats for being right on radical Islamic terrorism, I don't want congrats, I want toughness & vigilance. We must be smart!" 
 
 "I'm getting thousands of letters and tweets that I was right about the whole situation," Trump said on Fox News. "I mean, I've been right about a lot of things, frankly.... I was right about many, many things." 
 
 Trump is scheduled to give a speech about terrorism in New Hampshire on Monday afternoon, and he declined to provide details on the types of policies he might advocate, other than saying: "I'm calling for strength. I'm calling for intelligence."

– In the wake of the Orlando shooting one week ago, Donald Trump says the country should do what it has to do to prevent future such attacks, and he's putting racial profiling squarely on the table.
