The Transportation Security Administration is considering eliminating passenger screening at more than 150 small and medium-sized airports across the US, according to senior agency officials and internal documents obtained by CNN.The proposal, if implemented, would mark a major change for air travel in the US, following nearly two decades of TSA presence since the terrorist attacks of September 11, 2001, and comes as the Trump administration has stepped up screening measures for items such as laptops and tablets.Internal documents from a TSA working group say the proposal to cut screening at small and some medium-sized airports serving aircraft with 60 seats or fewer could bring a "small (non-zero) undesirable increase in risk related to additional adversary opportunity."The internal documents from June and July suggest the move could save 5 million annually, money that could be used to bolster security at larger airports.According to the proposal, passengers and luggage arriving from these smaller airports would be screened when they arrive at major airports for connecting flights instead of the current practice of joining the already screened population at the larger airport. The high-volume airports have greater capacities and more advanced security measures than smaller locations, the documents say.CNN terrorism analyst Paul Cruickshank said it was "stunning that this is even seriously being considered.""Al Qaeda and ISIS still regard aviation as a priority target -- that includes aircraft where you have fewer than 60 people on board," he said. "They would see that as a way to hit the headlines. They would see that as a way to inflict severe economic damage on the United States. If you have an aircraft of 50 or so people being blown out of the sky there is going to be a great amount of panic and there will indeed be significant economic reverberations, and of course significant loss of life.""This is so dangerous," a TSA field leader at a large airport said. The individual is not authorized to discuss the matter publicly.Two senior TSA officials, who asked not to be identified, expressed serious national security concerns over the proposal. They said the idea was explored as far back as 2011 and has been resurrected. The documents referred to some 150 small airports in addition to some midsize ones. TSA currently screens passengers at 440 airports, according to its website.The working group determined that the policy change would affect about 10,000 passengers who are screened by 1,299 TSA employees daily, which amounts to about 0.5% of the people who fly out of US airports on any given day. The report does not list specific airports that could be affected by the policy change.TSA spokesman Michael Bilello said the study reflects a recurring debate within the agency about its legal requirements."This is not a new issue," he said via email. "The regulations which established TSA does not require screening below a certain level, so every year is 'the year' that TSA will reconsider screening." Bilello did not respond to a request for the text of the regulations.The two TSA senior officials said the level of activity around the proposal this year -- the formation of a working group to conduct a risk and cost analysis -- mean this is more than an annual exercise.The documents said a TSA working group of 20 people, including a representative of the agency's administrator's office, met on June 21 to examine the potential risks of the policy change. An internal TSA memo dated July 17 from TSA Director of Enterprise Performance and Risk Strategy Jerry Booker to the TSA administrator's chief of staff, Ha Nguyen McNeill, outlines the group's findings. It contains no formal recommendation. 3761

The teenager who allegedly used a shotgun and a revolver to kill 10 people and wound 10 others at a Texas high school Friday admitted he didn't shoot people he liked and meant to kill the ones he did target, a probable cause affidavit says.Suspect Dimitrios Pagourtzis, 17, has cooperated with police, said Galveston County Magistrate Mark Henry said. Henry denied bail for the student, who is accused of capital murder of multiple people and aggravated assault on a public servant.Students at Santa Fe High School, not far from Houston in southeastern Texas, scrambled for safety after they heard shots just after class began Friday morning. Nine students and one teacher were killed, a law enforcement official told CNN.Pagourtzis said little during a video court appearance, answering "Yes, sir" when asked whether he wanted a court-appointed attorney. He was not asked to enter a plea.The probable cause affidavit says he told an investigator he spared people he liked because he wanted his story told.The alleged shooter used a shotgun and a .38 revolver that were legally owned by his father, Gov. Greg Abbott told reporters. Two school resource officers were on the campus and confronted the shooter "early on in the process," Abbott said.Live updates on the school shootingLatest developments? A student who survived being shot in the head tweeted: "I'm so greatful and blessed that god spared me today." Rome Shubert showed CNN affiliate KTRK where a bullet went in the back of his head and came out near his left ear.? A Pakistani exchange student, Sabika Sheikh, was killed, the county's embassy in Washington said.? One classmate told CNN the alleged shooter was "really quiet and he wore like a trench coat almost every day."? Abbott said investigators have found journals on a computer and cell phone owned by the suspect.? The governor offered his sympathies to the victims then called for lawmakers and others to come together to prevent more tragedies. "We need to do more than just pray for the victims and their families. It's time in Texas that we take action to step up and make sure this tragedy is never repeated ever again."? Retired Houston Police officer John Barnes was one of the people shot at Santa Fe High School, a hospital official said. Houston's police chief tweeted that he visited the hospital where Barnes was being treated and that Barnes was "hanging in there." The officer was working as a Santa Fe officer, a police union official tweeted.What we know about the shootingEarly morning attackGunfire erupted at the school, about 20 miles outside Galveston, not long after classes began around 7:30 a.m. CT, officials said. Authorities later found explosive devices -- including pipe bombs and pressure cookers -- in and near the school, the law enforcement official said.The suspect is believed to be a student. A second person -- also believed to be a student -- has been detained as well, Harris County Sheriff Ed Gonzalez said earlier.The male that Gonzalez described as a suspect was injured, a law enforcement official said on condition of anonymity.Investigators believe that the second person, an 18-year-old, may be an accomplice but not a shooter, a law enforcement official said.Two law enforcement officers are among the injured, according to a law enforcement source.One man is in critical condition with a gunshot wound in one of his arms, said David Marshall, chief nursing officer for University of Texas Medical Branch hospital.This is the 22nd US school shooting since the beginning of the year, and the third instance in eight days in which a gunman was on a school campus.Witnesses described students running from the school as they heard gunshots; they also described hearing an alarm at the school, though the sequence of events wasn't immediately clear.Authorities found explosive devices in the high school and in adjacent areas, said Walter Braun, Santa Fe Independent School District police chief. It wasn't immediately clear if any had exploded.Because the devices were found, Braun urged people in the city of about 13,000 people to "not touch any items that look out of place, and call 911" if they see something suspicious.Investigators Friday afternoon were searching a trailer where they believe the devices were assembled, a law enforcement source said.The school has been cleared of all students and staff, who have been directed to a nearby facility to reunite with their families, Braun said.Witness: Shooter fired gun in an art classAn armed person walked into an art class at the school and began firing what looked like a shotgun, a witness told KTRK.The witness told KTRK she saw a girl shot in the leg.Victims were being treated at three hospitals, authorities said. Eight people went to Clear Lake Regional Medical in Webster, Texas; two patients were treated at Mainland Medical Center in Texas City; and four patients went to John Sealy University of Texas Medical Branch in Galveston. It is unclear whether they were all wounded.Six of the eight patients at Clear Lake Regional were discharged by Friday afternoon.Witnesses describe hearing an alarm as well as gunfireAngelica Martinez, a 14-year-old student, told CNN she and her schoolmates were being evacuated at one point "like it's a fire drill.""We were all standing (outside), but not even five minutes later, we started hearing gunshots," she said. "And then everybody starts running, but, like, the teachers are telling us to stay put, but we're all just running away.""I didn't see anybody shooting, but like (the gunshots) were kind of spaced," Angelica said, adding she heard about four shots.A witness who spoke to KTRK also said she heard an alarm. She didn't specify if that was before or after the gunfire she described in the art class.She said she couldn't describe the shooter."I didn't look. I just ran," she said.Another student, Dakota Shrader, told CNN affiliate KPRC that she heard gunshots only after hearing an alarm in the school."I was in the history hallway, and as soon as we heard the alarms, everybody just started leaving following the same procedure as ... (a) practice fire drill," Shrader said, breaking into tears. "And next thing you know, we just hear ... three gunshots, loud explosions, and all the teachers are telling us to run."MaKenna Evans, a 16-year-old sophomore, told CNN she was in geometry class when the shooting started.First, she heard a fire alarm, she said. When the students got outside, her principal told them all to run.Evans said students hid behind a building across the street from the school.The high school has about 1,400 students, according to GreatSchools.org.Trump: Mass shootings have been 'going on too long in our country'Trump addressed the school shooting, saying that mass shootings have been "going on too long.""Unfortunately, I have to begin by expressing our sadness and heartbreak over the deadly shooting at Santa Fe High School in Texas," Trump said from the East Room of the White House. "This has been going on too long in our country. Too many years. Too many decades now."Trump said federal authorities are coordinating with local officials."We grieve for the terrible loss of life and send our support to everyone affected by this absolutely horrific attack," Trump said.Trump has ordered US flags at federal facilities be flown at half-staff.The-CNN-Wire 7385

The racial justice movement is inspiring hope and change.Two of the oldest hate fighting and civil rights nonprofits are joining forces to build ties between Black and Jewish people.“You can’t really fight one kind of hate unless you're going to fight all of them, right, so we can’t be saying anti-Semitism is bad and not be engaged right now in this great movement to challenge systemic racism,” said Shira Goodman with Anti-Defamation League Philadelphia.The Anti-Defamation League and National Urban League are kicking off the partnership in Philadelphia.They're starting a voting rights project trying to energize young voters.They're using young leaders from both groups to recruit younger poll workers and produce mailers and social media videos encouraging people to exercise one of the greatest tools to change.“We want to be able to give people accurate information and also hold each other accountable by having a voting plan, maybe having a buddy they are going to text back and forth, ‘did you go to the polls did you request your ballot?’”Philadelphia is just the start of this partnership for equality. They're looking at future projects to promote economic empowerment, equal access to justice, update hate crime laws and address discrimination in housing and employment.“It’s building on our shared histories as Blacks and Jews of having worked together, having both struggled in America and also saying we want to not sit on that history, we want to build a new future together,” said Goodman.The partnership and focus come at critical time for minorities which tend to face more voter suppression. 1624

The White House defended President Donald Trump's Sunday tweet that included a video of his supporters yelling the phrase "white power" at protesters at a Florida retirement community.On Sunday morning, President Donald Trump retweeted a video that was reportedly taken at The Villages, a large retirement community in central Florida. At one point in the video, a man in a golf cart adorned with Trump flags yells "white power" at anti-Trump demonstrators.The protesters can also be heard in the video shouting profanities at Trump supporters and also calling Trump a "Nazi" and "racist."Trump included a message in his retweet of the video, writing, "Thank you to the great people of The Villages." The tweet was live for more than three hours before it was deleted from his feed.Though the tweet was deleted, it sparked condemnations from some members of his own party. Sen. Tim Scott, R-South Carolina, called Trump's endorsement of the video "indefensible."In a statement on Sunday evening, White House spokesperson, Judd Deere defended the president's actions, saying that he "didn't hear" the racist language used in the video."President Trump is a big fan of The Villages. He did not hear the one statement made on the video. What he did see was tremendous enthusiasm from his many supporters," Deere said, according to CNN and The Associated Press. 1365
