WASHINGTON (AP) — A vehicle collision between U.S. and Russian forces in eastern Syria has left four U.S. troops with concussions. That's according to two U.S. officials who are speaking on condition of anonymity to provide details that haven't been made public yet. It's the most violent skirmish in months between the two forces. One official says Russian vehicles sideswiped a light-armored U.S. military vehicle, injuring four Americans. The official says two Russian helicopters flew above the Americans, and one of the aircraft was within about 70 feet the vehicle. There have been several other recent incidents between the American and Russian troops who all patrol in eastern Syria, but officials describe this one as the most serious. 752

WASHINGTON (AP) — President Donald Trump and Homeland Security chief Kirstjen Nielsen never quite clicked personally as the president chafed at her explanations of complicated immigration issues and her inability to bring about massive changes at the U.S.-Mexico border.With Nielsen's departure now considered inevitable, her eventual replacement will find there's no getting around the immigration laws and court challenges that have thwarted the president's hard-line agenda at every turn — even if there's better personal chemistry.The list of potential replacements for Nielsen includes a career lawman, two military officers and former acting U.S. Immigration and Customs Enforcement head Thomas Homan — a tough-talker who echoes Trump's border rhetoric."A good DHS person ought to be able to scare America" about heroin coming over the border and illegal crossings, former Trump campaign adviser Barry Bennett said. "But, the system is so against you legally and structurally."Trump soured on Nielsen in part over frustrations that she has not been able to do more to address what he has called a "crisis" at the U.S.-Mexico border. Trump has seized on statistics about illegal border crossings that have grown on her watch after reaching a record low early in his term. More than 50,000 people were detained at the southwest border in October — the highest monthly total since 2014 and up dramatically from 11,000 in April 2017."It's a tough job. You're someone who has to get good numbers on border crossing. He's always looking for that and it's tough," Bennett said.But illegal border crossings could also be tied to the seasons — some experts argue that more migrants make the dangerous journey through the desert when it's not as hot. And Nielsen has largely carried out the president's wishes, including pushing for funding for his border wall and defending the administration's now-abandoned practice of separating children from parents. She also moved to abandon long-standing regulations that dictate how long children are allowed to be held in immigration detention, and was working to find space to detain all families who cross the border. She limited what public benefits migrants can receive, and last week put regulations in place that circumvent immigration law to deny asylum to anyone caught crossing the border illegally. Nearly everything has been challenged or watered down by the courts."I don't think they're going to get the magic person," said Andrew Selee, president of the Migration Policy Institute, a nonpartisan think tank that studies migration issues. "Nielsen had been fairly hard-line implementing what Trump wants, but she's not willing to skirt around the law to do it."And it's not just about policy.Trump has also told allies that he never fully trusted Nielsen, whom he associated with President George W. Bush, a longtime foe. And he has told those close to him that he feels, at times, that she has stronger loyalty to her mentor — chief of staff John Kelly — than to the president. On occasions when she has tried to explain the complicated legal challenges associated with instituting some of his policies, Trump has exploded, belittling her in front of colleagues and blaming her for not being able to skirt the law.Trump had been expected to dismiss Nielsen as soon as Tuesday as part of a post-midterm elections shakeup that is likely to include a slew of other departures.But her departure has been postponed for now in part because there was no obvious successor, according to two people familiar with the discussions who were not authorized to speak publicly and spoke on condition of anonymity. She has no deputy secretary, and the next in line would be Claire Grady, the undersecretary of homeland security for management.Trump said in an interview with The Daily Caller on Wednesday that he'd make a decision on homeland security "shortly."Potential candidates include U.S. Customs and Border Protection Commissioner Kevin McAleenan, and two military officers — Transportation Security Administration head David Pekoske, formerly of the Coast Guard, and Maj. Gen. Vincent Coglianese, who runs the Marine Corps Installations Command, according to people familiar with the discussions.A Customs official didn't return a call seeking comment. A spokesman for Coglianese said he had not been approached by anyone regarding a position with DHS and was focused on his current job.Pekoske said at an unrelated news conference that Nielsen was a strong leader."I have an outstanding relationship with Secretary Nielsen," he said.Homan is regarded as a top pick, according to people familiar with the discussions. He was nominated by Trump to lead Immigration and Customs Enforcement, but stepped down before he was confirmed, and it's not clear if his nomination would pass the Senate or if he'd even be up for the job. He left in part because he wanted to spend more time with his family."I won't speculate what the president will do," he said on Fox News, but praised Nielsen as a "strong secretary" and said she was succeeding in a difficult job."It's a 24/7/365 job," Homan said. "Fifty percent of America hates you 100 percent of the time, you can't win on this topic because it is so divisive." 5264

VISTA, Calif. (KGTV) - Prosecutors presented evidence Thursday against a man suspected of killing his girlfriend in Cardiff in an effort to send the case to trial. Late in the day, a judge decided there was enough evidence for the case to move forward.Henry Cowen is charged with murder in the death of 43-year-old Sabrina Lukosky. During his preliminary hearing in Vista court, attorneys heard from multiple witnesses, including a DNA expert who tied Cowen to the crime scene. Lukosky’s mother requested a welfare check in October 2019 after not hearing from her daughter for several days. RELATED: North County man accused of killing girlfriend tried to escape the country, prosecutors sayOfficers found Lukosky’s car in front of the granny flat she shared with Cowen and reported a foul smell coming from the home. A search warrant was executed a few days later, and led to the discovery of Lukosky’s body. Police said there were signs of a violent struggle in the couple’s bedroom. "There was a broken stick, a bottle that had been broken, some amount of blood, and the victim had a 1.5-inch vertical gash to her forehead," said Deputy District Attorney Marnie Layon. The San Diego County Medical Examiner’s office later determined Lukosky died of blunt force trauma and strangulation. Prosecutors believe Cowen left San Diego County and traveled to Los Angeles, then took a Lyft to Riverside County. They also said Cowen tried to leave the country with the help of his children’s mother. RELATED: Friends remember Encinitas woman, police say, was killed by her boyfriendThe Fugitive Task Force arrested Cowen in Riverside County on Oct. 11. He has a criminal record including assault, kidnapping, and torture, authorities told 10News. 1747

VISTA, Calif. (CNS) - A 54-year-old Poway man accused of killing a young woman in Carlsbad 33 years ago pleaded not guilty Tuesday to charges of murder and rape.James Charles Kingery faces 33 years to life in state prison if convicted of all charges stemming from the killing of 26-year-old Julia Hernandez-Santiago, according to the San Diego County District Attorney's Office.The victim's body was found on Oct. 10, 1987 on an ivy-covered embankment in the 2100 block of Alga Road, Carlsbad police spokesman Jodee Reyes said.The San Diego County Medical Examiner's Office determined the cause of death was asphyxiation due to strangulation.While a suspect was not identified at the time of the killing, investigators said technological advances eventually led to Kingery's arrest.In March, San Diego County sheriff's deputies arrested a man on narcotics and weapons violations and took a DNA sample from him, as required by law based on his alleged offenses, Reyes said. Then in May, the sheriff's crime lab notified Carlsbad police that DNA samples from the 1987 murder case were a match for Kingery, who was arrested July 22.A suspected motive for the killing has not been disclosed."When a murder goes unsolved, not only is justice delayed, but families are left in turmoil with no closure," District Attorney Summer Stephan said in a statement. "Working with Carlsbad Police Department detectives, who never gave up, our office is bringing a measure of justice to Ms. Hernandez-Santiago's family and giving hope to other victims in unsolved cases."Kingery is being held on million bail. He's due back in court Sept. 4 for a readiness conference. 1662
