WASHINGTON (AP) — The National Guard of the District of Columbia is investigating the use of one of its helicopters to make a "show of force" against protesters near the White House. The helicopter is normally designated for use in medical evacuations. But on Monday night, it hovered low enough in downtown Washington to create a deafening noise and spray protesters with rotor wash. The commanding general of the D.C. Guard says he's directed the investigation. It comes as the federal government has promised to maximize the federal law enforcement presence in the nation's capital.  603

WASHINGTON, D.C. – The House Committee on Foreign Affairs will hold a hearing Tuesday morning on Iran. Members of the committee are working to find answers to questions that continue to swirl regarding the intelligence that led to the U.S. drone strike that killed Iranian Gen. Qassem Soleimani earlier this month.The committee had invited Secretary of State Mike Pompeo to testify at the hearing to provide context on the use of military force and the overall strategy in the Middle East, but he rejected the invitation. In response, Chairman Eliot Engel (D-N.Y.) said in a 587

When Neil Armstrong and Buzz Aldrin stepped on the moon on July 20, 1969, there's no doubt that the entire human race was in awe. For thousands of years, humans had imagined leaving Earth and visiting worlds outside of Earth. That day had finally come.The 268

Vitamin E acetate, in combination with THC, may be to blame for a national outbreak of e-cigarette-related lung injuries that's linked to dozens of deaths, according to US Centers for Disease Control and Prevention officials.Dr. Anne Schuchat, the principal deputy director of the CDC, said she would characterize it as a breakthrough in the agency's investigation, although more tests are necessary."These new findings are significant," Schuchat said during a press briefing on Friday. "We have a strong culprit."There is still more work to do and the CDC said it is continuing to test for a wide range of chemicals."This does not rule out other possible ingredients," Schuchat said. "There may be more than one cause."The CDC says its tests found vitamin E acetate in samples taken from 29 patients who were sick with vaping-related illness in 10 states. THC, or tetrahydrocannabinol, the primary psychoactive component of the cannabis plant, or its metabolites were detected in 23 of 28 patients.During the press briefing, CDC's Dr. James Pirkle described vitamin E acetate as "enormously sticky" when it goes into the lungs, and it "does hang around." Pirkle said it wouldn't be unusual for THC to be absent from some of the samples because it leaves the lungs faster. He added finding THC in 82% of the samples from 28 patients was "noteworthy."In September, New York health officials linked cases of severe lung illness to vitamin E acetate in cannabis-containing vaping products. At the time, investigators said it was "a key focus" of the state's investigation into the illnesses.An investigation into the link between vaping and severe lung illnesses has yielded the discovery of extremely high levels of the chemical vitamin E acetate in nearly all cannabis-containing vaping products that were analyzed, New York health officials said Thursday.Until the investigation is complete, the CDC suggests people refrain from using all vaping products with THC, no matter where people buy them. The investigation has found that many of these products patients used were bought online or received through friends or family, rather than through vaping shops or at licensed THC dispensaries.Vitamin E is used in several products, such as lotions and in supplements, but the CDC said there is a "big difference" in putting vitamin E on the skin or swallowing it in pill and in inhaling the oily vitamin.Dr. Jennifer Layden, the chief medical officer and state epidemiologist with the Illinois Department of Public Health, said in the press briefing that in her state, they found the majority of cases of the people who were sick used THC, and that their materials came from "informal sources." In Illinois, she said, they had not had any cases associated with the state's medical marijuana program.So far, there have been 2,051 cases of vaping associated illnesses, reported in every state, except for Alaska, as of November 5. States have reported at least 40 deaths. 2979

U.S. Immigration and Customs Enforcement is scaling back the aggressive operations it launched under President Donald Trump as the country contends with the new coronavirus outbreak.ICE says that starting Wednesday it is focusing its efforts on tracking down people in the U.S. without legal authorization who pose a risk to public safety or would be subject to mandatory detention on criminal grounds. The agency had been aggressively detaining anyone in the country without authorization as part of stepped up enforcement under the Trump administration.The agency said in a statement that its investigations unit will focus on public safety and national security. That would include drug and human trafficking as well as anti-gang operations and child exploitation cases.ICE said the change was temporary and intended to ensure the welfare and safety of the public and its agents.It will not carry out enforcement operations at or near health care facilities except in “the most extraordinary circumstances” during the crisis. 1040
