As Republicans absorb the shock of losing the House of Representatives, the GOP leadership race in the chamber is ramping up to determine who will take over the position of No. 1 House Republican after outgoing House Speaker Paul Ryan leaves.Rep. Jim Jordan, the co-founder of the conservative House Freedom Caucus, announced a bid for minority leader on Wednesday, setting up a challenge to Rep. Kevin McCarthy, the current No. 2 Republican and House majority leader, who is viewed as the favorite to succeed Ryan."I think we have to match the President's intensity on changing this town as we move forward," Jordan told CNN on Wednesday when asked about his bid for minority leader and a challenge to McCarthy.Asked about how House Republicans can counter a Democratic majority pursuing oversight of the President and the administration, Jordan said, "You stand up for the truth. You stand up and defend the White House and the President." He added that Republicans will have to "show the American people the difference in where we would like to take the country and earn back their trust and earn back the majority."According to a source familiar with his plans, Jordan is expected to make the pitch that Republicans would need a fierce attack dog as minority leader to fight against Democrat oversight efforts, and Jordan has already proven he has a loud and aggressive bark.House Republicans are set to hold their leadership elections on Wednesday of next week, a day after they return to Washington.McCarthy has yet to formally announce his own bid for minority leader. Jordan, meanwhile, is viewed as a long shot for the House GOP leadership post.It's unclear yet if House Majority Whip Steve Scalise could also mount a bid for minority leader.Scalise has said that he would not challenge McCarthy in a race for speaker, but when asked recently whether he would challenge the current No. 2 Republican in a race for minority leader if Republicans lost the House, he declined to speculate on the hypothetical."I've never been in the speculation game," Scalise told Roll Call, adding, "when Paul said he was going to step down — I said I'd support Kevin. And I haven't talked about all the things that might happen and what I might run for."With House Republicans in the minority, there may be a match-up between Rep. Cathy McMorris Rodgers and Rep. Liz Cheney for the position of GOP conference chair. McMorris Rodgers currently holds that position, but Cheney on Wednesday formally announced her candidacy for the spot in the next Congress."I am asking for your support to be House Republican Conference Chair because I know we can and must prevail, and I want to lead the effort to build a new and effective House GOP communications operation," Cheney wrote in a letter to members on Wednesday.McMorris Rodgers has not yet announced what she plans to do.Republican Study Committee Chairman Mark Walker will run for GOP conference vice chair.Walker was contacting his colleagues Wednesday morning and letting them know he is running, according to his spokesman, Jack Minor. 3087

At 3 p.m. ET on Monday, November 26, a group of researchers will be really sweating. The NASA InSight spacecraft will try to land on Mars.After six months of flight, the lander component of the probe will detach itself from the cruise stage and head into the atmosphere. The lander component initially looks a fair bit like the re-entry capsule used in the 1960s and 1970s for the Apollo moon missions -- sort of conical, with a smooth and flat bottom. That bottom is a crucial heat shield that is designed to protect the probe as it passes through the thin Martian atmosphere.The landing is a devilishly difficult feat. The landing capsule has to batter its way through the atmosphere. It will fly through the Martian air at an initial speed of 12,300 mph, and it must hit the atmosphere at an angle of precisely 12 degrees. Any shallower, and the probe will bounce off into deep space. Any steeper, and the probe will burn itself up in a spectacular and fiery death. The probe will first touch the atmosphere six minutes and 45 seconds before landing. During this phase, it will experience acceleration 12 times that of the Earth's gravity. Were the probe a 150-pound human, during the flaming descent, it would weigh nearly a ton.About 3? minutes after the probe hits the atmosphere, a parachute will deploy, slowing down the probe even more. Fifteen seconds later, explosives will blow the heat shield off, exposing the actual InSight probe hidden inside. Ten seconds after the heat shield falls away, the probe will extend its legs, much like an airplane extends its wheels before touching down.The probe will fall for an additional two minutes attached to the parachute and protected by its conical shell. About 45 seconds before InSight lands, it will drop out of the shell and fall toward the surface. As soon as it leaves the shell, its landing rockets will ignite.The actual InSight probe looks a little bit like the Apollo moon lander, with three legs to support it and a boxy top. The rockets will slow it further and stop any remaining horizontal motion. Then, about 15 seconds before touchdown, the InSight probe will descend at a speed of 8 feet per second, before hopefully touching down gently on the Martian surface.The entire landing sequence will take about seven minutes to occur. A radio signal from Mars to Earth currently takes about eight minutes and seven seconds to get here. So the complete landing process will take place before we find out if it was successful. It will be done automatically, entirely by the probe itself. For the scientists and engineers who designed InSight, this is called "seven minutes of terror."And they are right to be worried. Mars is a graveyard of failed probes. There have been 44 attempts by various national space agencies to land on Mars. Eighteen have been successful. Twenty-three have not. Three have achieved orbit but failed at a landing.So, what does InSight hope to achieve? Well, as it happens, a lot. But it's different than the intrepid Curiosity probe, which NASA landed in 2012. InSight will not move around. Instead, it will stay put and tell us of the interior of Mars.One thing it will do is emit radio waves that we can monitor on Earth. By making careful measurements of how the frequency of the radio waves change, we will be able to measure the degree to which Mars wobbles as it rotates. That will tell us something about the core of the planet, specifically its makeup and information on the degree to which it is molten.InSight will also deploy a seismometer to listen for marsquakes (like earthquakes, but Martian-style) and for impacts of meteors on the planet. Information gleaned from the waves the seismometer detects will tell us more about the planet's interior.The third thing InSight will do is to dig below the planet's surface. Using a jackhammer, the probe will drill down 5 meters (16 feet) into the planet and, basically, it will take the planet's temperature.There are many reasons this is interesting. Taking the temperature at that depth will allow planetary scientists to determine how much heat is escaping from Mars. More broadly, this measurement will allow a clear determination of the temperature of the planet much closer to the core.This information will tell us a lot about how Mars formed, which, in turn, will add to the information of how rocky planets, including our own Earth, typically develop.And if you're more of an explorer kind of person and not so interested in Martian geology, it will also tell us how warm the planet is at modest depths, which will tell us if there is any chance of liquid water on the planet. Perhaps obviously, if the Martian subsurface is warm enough, any buried water will be in liquid form and not ice. Finding liquid water would be the key discovery that would make Martian exploration relatively easy. A relatively recent possible discovery of a buried Martian lake was promising, but the data was not conclusive. Knowing that the ground is warm would be very comforting to possible future explorers.Exploring the solar system is the first step toward exploring the stars. The InSight probe will give us --well -- insight into whether this is something that humanity will achieve in the foreseeable future.And maybe Elon Musk's bet on him getting to Mars will become true. 5329

BALDWIN, La. — New details are emerging as law enforcement investigates the death of a 15-year-old boy who died under suspicious circumstances in Louisiana.KATC obtained police reports from Oct. 30 when the teen, Quawan “Bobby” Charles, was reported missing from his home in Baldwin and was found dead four days later near Loreauville.Records show that Charles’ mother contacted the St. Mary Parish Sheriff’s Office around 8:10 p.m. on Oct. 30 to report that her son was missing. The mother stated that her son did not come home and had on a West St. Mary High School jacket.SMPSO then dispatched an officer with the Baldwin Police Department to the 600 block of MLK Street in Baldwin.At 8:45 p.m., BPD spoke with Charles’ father and mother who said that he was last seen at around 4 p.m. Police then entered Charles’ name into the National Crime Information Center, which is a nationwide database used by law enforcement to locate missing persons, as a missing juvenile.According to a police report from BPD, Charles’ mother said that she was not present at the time that he went missing because he was staying with his father because the two did not live together. Charles had only recently been allowed to stay with his father for the two weeks prior to his disappearance.Charles’ father told police that he went to the store around 4 p.m., but after returning a few minutes later, he attempted to knock on the door to Charles’ room several times without a response.The father told police that he then used a tool to gain entry into the room and discovered the teen was missing.Both parents told police that Charles had not been a problem at home but had been placed on a curfew by the 16th Judicial District Court because of disciplinary problems at school.The parents told police that Charles did not have any friends and had never left home before without them knowing about it.The police state in the report that there was a football game taking place at West St. Mary High School in Baldwin as well as an event called Boo on the Bayou in Franklin. Charles’ father told police he would begin searching those areas. However, he later contacted SMPSO and said he was not able to locate Charles’ at either location.This is when police entered Charles’ name into the NCIC database as a missing juvenile while being on the lookout for him.Charles’ mother then told police that she would be heading back to her home in Youngsville to check and see if he had returned there.Charles was found dead four days later on Nov. 4 in a rural area off Ed Broussard Road near Loreauville. Since then, some family members are claiming Charles was murdered, and believe police ignored their initial cries for help.The family tells KATC they were told by investigators that Bobby drowned, but that they don't believe that. They cite a graphic photo of his body circulating online.Family members also say Charles left his home with a 17-year-old friend and the teen's mother without permission.Several dozen people, including Bobby's family, people from the community, and an organization called Stand Black, gathered on the courthouse steps Wednesday evening. They're demanding a thorough investigation of the case.The Iberia Parish Sheriff's Office is handling the investigation. Deputies have not said if Charles was killed. IPSO says it's being investigated under suspicious circumstances. Deputies have interviewed several people in connection with the case and collected physical evidence, but so far no arrest has been made.This story was originally published by staff at KATC. 3578

  

As the FBI and US law enforcement agencies turn to the catching the serial mailbomber, or mailbombers, terrorizing those who have been labeled by President Donald Trump as political enemies, it's interesting to follow in their steps and examine what we know about the now 12 packages that have been intercepted.All those we have seen were all in manila envelopes, for instance, with the same return address. They all had six forever stamps, which was enough to get some to mail sorting facilities, but another needed more postage. They all had the same return address, with a misspelled name for Debbie Wasserman "Shultz," not Schultz, a Democratic congresswoman from Florida who is the former chairwoman of the Democratic National Committee.There are images of five of the packages, one of which -- one of the packages sent to Democratic Rep. Maxine Waters of California -- was shared by both DC Police and the FBI on social media.Related: The manhunt - FBI treating serial bomber as domestic terrorism  1017

  

Avocado pits as a dye? Well, that's precisely what Chipotle Mexican Grill is going to use on their new clothing and accessories line Chipotle Goods.According to a news release that was released Monday, the company will use the pits that are leftover from some of their restaurants that will be "upcycled" to create "natural avo dyed goods.""We know people are looking to celebrate their passion for Chipotle, and we set out to create a line of products with the same thoughtfulness, care, and attention to detail that we use in our kitchens," said Chris Brandt, Chipotle chief marketing officer in the news release. "With Chipotle Goods, our fans can get quality items that support sustainable agriculture and represent our mission of cultivating a better world."The gender-neutral collection will feature items like avocado lined jean jackets, avocado dyed t-shirts and sweatshirts, graphic tees that are customizable, which will allow fans to "select their ingredients as they do in the restaurant."To create the plant-based dye, the company said the pits would be simmered in water.The stains will vary in color, the company said."Each unique piece from the avo dyed collection requires five avocado pits, equivalent to five orders of guac, depending upon the season and size of the fruit," the fast-food chain said in the release.The line will be released to the general public on Tuesday and can be accessed by going to www.chipotlegoods.com. 1455
