The wild ride on Wall Street just got crazier.The Dow dropped about 345 points, or 1.4%, on Tuesday, completely reversing a 244-point gain from early in the day. The selloff followed Monday's 670-point spike.The Nasdaq plunged nearly 3% -- wiping out nearly all of Monday's huge gains for the tech sector. The Nasdaq is now up just 1.5% on the year.Facebook, Twitter, Tesla and Nvidia all fell sharply. Netflix tumbled 6%, its biggest decline in two years."We started bleeding when large tech got hit hard," said Art Hogan, chief market strategist at B. Riley B.Investors poured money into bonds Tuesday. The 10-year Treasury yield slipped to 2.77%, the lowest since early February.But the sinking yields also narrowed the closely-watched gap between short and long-term rates, known as the yield curve."That has persistently been a signal of an economic slowdown," said Hogan. "I don't think that's the case here."A "flattening" yield curve also makes it harder for banks to make money on the difference between what they lend out and pay interest on. Bank of America, Wells Fargo and PNC fell more than 2% apiece.The-CNN-Wire 1135

The US House of Representatives passed a bill Wednesday to fund more security at schools, exactly one month after a gunman killed 17 people at a high school in Parkland, Florida, and as thousands of students take part in a national walkout in protest of gun violence.While the bill had bipartisan support, many Democrats were frustrated that it doesn't include any gun control measures."This is a pretense that we are doing something while assuring the NRA that we aren't doing anything," Rep. Steny Hoyer of Maryland, the second ranking Democrat in the House, told reporters Tuesday.The vote was 407-10. The bill attempts to curb school violence by providing more training for school officials and local law enforcement to respond to mental health crises, as well as, among other things, money to develop anonymous reporting systems for threats and deterrent measures like metal detectors and locks.Many Democratic lawmakers pressed Republican leaders to bring up gun control measures to expand background checks and ban assault weapons, but House GOP leaders continue to say they will wait to see what, if anything, the Senate can pass.In the Senate, the Judiciary Committee held a hearing on the Florida shooting and failures by the FBI and law enforcement to act on warning signs displayed by the gunman before the attack."In the wake of the Parkland attack, this committee has an obligation to find out what happened," said Senate Judiciary Committee Chairman Chuck Grassley, an Iowa Republican, in his opening remarks. "We must hold government to account for its failures, and make sure plans are in place to avoid future tragedies. And we must rally around consensus, evidenced-based solutions that will protect our nation's most valuable resource — its youth — from violent attacks."Both the hearing and the vote happened the same day students across the country are holding walkouts to commemorate the Parkland shooting anniversary and call for more action gun control measures. In Washington, global advocacy group Avaaz placed 7,000 pairs of shoes on the Capitol lawn to represent gun violence victims since the 2012 Sandy Hook Elementary School massacre. Protesters are demonstrating at the Capitol and in front of the White House on Wednesday.Both of Florida's senators -- Republican Marco Rubio and Democrat Bill Nelson -- testified at the hearing. The two men have also teamed up on legislation that would encourage states to adopt so-called red flag laws, which would give law enforcement the authority to seize guns from people who pose a threat to themselves or others.It's one of many gun control bills proposed by members on both sides of the aisle, but most efforts have largely stalled.President Donald Trump reiterated his support last weekend for a bill by Sen. John Cornyn of Texas, the No. 2 Republican in the Senate, and Democratic Sen. Chris Murphy of Connecticut that would encourage states and federal agencies to enter more data into the National Instant Criminal Background Check System, known as "Fix NICS."It was first introduced last fall after the Sutherland Springs, Texas, church shooting but it has seen renewed attention since last month's Florida shooting. While the bill currently has more than 60 cosponsors -- a normal indicator that it could avoid a filibuster -- many Democrats want to open up the legislation to amendments, and it's unclear how Republican leaders will proceed."I'm extremely interested in seeing Senator Cornyn's Fix NICS bill passed and a significant school safety bill passed," Senate Majority Leader Mitch McConnell told reporters on Tuesday. "The best way to get that done is still under discussion. But I'm anxious to pass both of them, and pass both of them soon."The witness list at the Senate Judiciary Committee hearing also included David L. Bowdich, the acting deputy director of the FBI, as well as Ryan Petty, whose daughter was killed in the Florida shooting, and Katherine Posada, a teacher at the school, Marjory Stoneman Douglas High School.And while there were no gun industry witnesses at the first hearing since the shooting, they loom large in the debate and play a critical role in lobbying members of Congress and rallying their supporters across the country during elections.The House bill, the STOP School Violence Act, aims to provide more training for school officials and local law enforcement to respond to mental health crises, as well as, among other things, money to develop anonymous reporting systems for threats and deterrents like metal detectors and locks.It does not include many of the components of a proposal unveiled by the White House -- most notably it does not include any provisions to arm teachers. House Republicans have largely ignored the President's plan, especially since he publicly declared that the major legislation the GOP-controlled chamber passed in December to loosen concealed carry rules was not something that could pass as part of broader gun legislation."This is about schools but it's not just about schools," Rubio told reporters Tuesday at a news conference about the Senate version of the bill. "When someone is determined that they're going to commit an act of violence, it could be in a school, it could be in a mall, it could be in a movie theater, it could be in an airport, it could be at a stadium. So what we're really focused on here more than anything else is identifying the people that are going to commit a violent act irrespective of where they're going to commit it and stopping them before they do it." 5558

The weekslong search for Mollie Tibbetts, a 20-year-old Iowa student who disappeared while jogging, came to a grisly end Tuesday when a man guided investigators to a body in a cornfield.While authorities have yet to confirm the body is Tibbetts, they arrested Cristhian Bahena Rivera, 24, on first-degree murder charges.The discovery dashed the hopes of family and friends who had scoured Poweshiek and nearby counties as rewards grew to nearly 0,000. Tibbetts, officials said, is believed to have been abducted on July 18 as she went out for an evening jog.Rivera, who's an undocumented immigrant, told them Monday that he saw and pursued her, getting out of his car and running beside Tibbetts. She warned him she would call police, officials told reporters Tuesday.The suspect, who said he blacked out at some point, led authorities to the field Tuesday morning, they said. A body, dressed in Tibbetts' clothing, was covered in corn leaves.It is unclear why Rivera killed Tibbetts, said Rick Rahn, special agent in charge at the Iowa Division of Criminal Investigation."I can't really speak to you about the motive," Rahn said. "I can just tell you it seems that he followed her and seemed to be drawn to her on that particular day and for whatever reason he chose to abduct her." 1294

The Trump administration is pushing back on a New York Times report that Education Secretary Betsy DeVos is looking into a plan that would allow states to use federal funding to buy firearms for teachers.On Wednesday, the Times reported that the Education Department was considering using a grant program called the Student Support and Academic Enrichment Program as a way to give federal funding for firearm purchases to states or school districts. The report cited multiple people with knowledge of the plan.A senior administration official told CNN that the idea laid out in the Times report did not originate with the Department of Education or DeVos. That official said the department received a letter from the Texas state Department of Education asking if the funds from a federal grant program could be used to purchase firearms. It was circulated to departmental lawyers and researchers for guidance, according to the official. The department ultimately chose not to respond, the official said.The official added that DeVos thinks that Congress should take action to clarify whether or not using the grant funding to buy guns is permissible. Moreover, the Education Department believes the grant program is intentionally vague to give school districts flexibility, and the idea of purchasing firearms was likely not considered when it was written, according to the official.In response to the Times report, Education Department spokeswoman Liz Hill told CNN that "the department is constantly considering and evaluating policy issues, particularly issues related to school safety. The secretary nor the department issues opinions on hypothetical scenarios."The discussion around arming teachers has been a deeply controversial one. President Donald Trump floated the proposal to arm educators and school staff on multiple occasions in the wake of the deadly school shooting at Marjory Stoneman Douglas High School in Parkland, Florida in February 2018."If you had a teacher who was adept with the firearm, they could end the attack very quickly," Trump said during a listening session on school safety a week after the shooting.The idea of arming school staff has been met with sharp condemnation.Former Congresswoman Gabrielle Giffords said in a statement Wednesday that "arming teachers is not a solution.""It recklessly puts American children in even more danger," she said in response to the Times report. "It's time for Americans to find the courage to take on the powerful and fight for our own safety."The American Federation of Teachers and the National Education Association also lambasted the proposal. Nicole Hockley, whose six-year-old son was killed in the 2012 Sandy Hook Elementary School shooting, took the microphone and told Trump she would rather arm teachers with ways to prevent shootings in the first place rather than with a firearm.Despite the criticism, Trump doubled down on the proposal on several subsequent occasions, and in March, the Trump administration proposed providing some school personnel with "rigorous" firearms training.In the wake of the Parkland shooting, the Trump administration also created a federal school safety commission, which is chaired by DeVos. In June, she testified before a congressional committee that the commission would not focus on looking at the role the role of guns in school safety. That stance was panned during a public forum. Democrats on the House Committee on Education and the Workforce have called on DeVos to explain how the commission will explore the role of guns."The Commission was charged with recommending policies and funding proposals to prevent school violence," 17 members of the committee wrote in a letter in June. "A core element of combating school violence is addressing gun violence, both in school and in our communities."The-CNN-Wire 3843
