A watchdog report ordered in 2012 by Dr. Ronny Jackson — President Donald Trump's nominee to lead the Department of Veterans Affairs — found that he and a rival physician exhibited "unprofessional behaviors" as they engaged in a power struggle over the White House medical unit. The report, reviewed Tuesday by The Associated Press, suggested the White House consider replacing Jackson or Dr. Jeffrey Kuhlman — or both. Kuhlman was the physician to President Barack Obama at the time. Get More

A 25-year-old who plowed a van into a crowded Toronto sidewalk was ordered held Tuesday on 10 counts of murder and 13 of attempted murder as Canadian authorities and the public sought to make sense of what appeared to be one of the deadliest mass murders in the country's modern history. Alek Minassian showed little overt emotion as he made a brief appearance in a Toronto courtroom in a white jumpsuit and handcuffs. The judge ordered him detained without bond and scheduled the next hearing for May 10. Police, meanwhile, still appeared to be gathering evidence. About 20 officers made their way down the van's deadly path on Yonge Street searching for any evidence. Nearby, mourners had put together a makeshift memorial to the victims. Get More

Authorities said Monday that three Mexican film students who went missing in March in Guadalajara were kidnapped, tortured and killed, and their bodies were dissolved in acid, NBC News reported. Javier Salomón Aceves Gastélum, Daniel Díaz, and Marco Ávalo were last seen on March 19 in the municipality of Tonala, in the state of Jalisco, filming a class project during their Spring Break. The three aspiring filmmakers were students at the Universidad de Medios Audiovisuales. According to state prosecutors, their car broke down during the trip and they were later kidnapped by gunmen from the Jalisco New Generation Cartel (CJNG), who confused them for members of a rival gang. Academy Award winning director Guillermo del Toro, who is a native of Guadalajara, expressed outrage on social media in response to the killings. "Words can't explain the dimension of this madness. 3 students are killed and dissolved in acid. The "why" is unthinkable, the "how" is terrifying,” the "Shape of Water" director tweeted.

Federal health officials on Tuesday announced a nationwide crackdown on underage use of a popular e-cigarette brand following months of complaints from parents, politicians and school administrators. The Food and Drug Administration issued warnings to 40 retail and online stores as part of a monthlong operation against illegal sales of Juul to children. Investigators targeted 7-Eleven locations, Shell gas stations and Cumberland Farms convenience stores as well as vaping shops. FDA regulators also asked manufacturer Juul Labs to turn over documents about the design, marketing and ingredients of its product. The rare request focuses on whether certain product features are specifically appealing to young people. Get More

Accompanied for the first time by his wife of more than 50 years, Bill Cosby walked into a courthouse Tuesday morning ahead of closing arguments in his sexual assault retrial. Camille Cosby had been absent from the courtroom as prosecutors called a series of women to the stand who testified her husband drugged and sexually assaulted them, but she was by his side Tuesday for the trial's conclusion. The jury that will start deliberating Cosby's fate has heard the comedian described over the past two weeks both as a "serial rapist" and a con artist's victim. Get More

One month ago President Donald Trump surprised many, including some in his own administration, by announcing, "We'll be coming out of Syria, like, very soon. Let the other people take care of it now." He insisted that the time had come for the U.S. military to shift its focus away from Syria. But on Tuesday, it was clear that something or someone had changed Trump's mind. The president said at a White House news conference with French President Emmanuel Macron at his side that before the U.S. withdraws from Syria, "we want to leave a strong and lasting footprint." This long-term approach, he added, was "a very big part" of his conversation with Macron, who told reporters that he and Trump now agree that the Syria problem involves more than Trump's priority of ridding the country of Islamic State extremists.

Travis Reinking's erratic behavior began years before police say he showed up without pants at a Waffle House restaurant and killed four people with an assault-style rifle. The onetime construction crane operator bounced between states and suffered from delusions, sometimes talking about plans to marry singer Taylor Swift, friends and relatives told police. He was arrested outside the White House last year after asking to speak to President Donald Trump, and his bizarre actions seemed to intensify in recent days with a car theft. Get More
