Welcome to CNN's fact check of the sixth Democratic presidential primary debate.Thursday's debate was hosted by PBS and Politico, and came a day after the House of Representatives impeached President Donald Trump. It also came the same day the House voted to approve Trump's US-Mexico-Canada Agreement.Just a month and a half before the Iowa caucuses, the three-hour debate offered candidates a chance to delve more deeply into their policy disagreements than they had in their five previous clashes.Only seven candidates met the party's thresholds for qualification this time: former Vice President Joe Biden, Vermont Sen. Bernie Sanders, Massachusetts Sen. Elizabeth Warren, South Bend, Indiana, Mayor Pete Buttigieg, Minnesota Sen. Amy Klobuchar and businessmen Andrew Yang and Tom Steyer.Klobuchar on Hillary Clinton margin of victoryKlobuchar said, "If you look at the poll[s], at the state that knows me best, and that is the state of Minnesota, it showed in the state that Hillary had her lowest margin of victory, it showed that I beat Donald Trump by 18 points."Facts First: She's basically right about the polls, but she's wrong about the 2016 election results.In 2016, Hillary Clinton barely defeated Donald Trump in Minnesota, winning by 1.6 percentage points. It was extremely close, but it wasn't her tightest margin of victory, as Klobuchar claimed. That state was New Hampshire, where Clinton 1421

Two agents with the North Carolina State Bureau of Investigation's Bomb Squad were injured, one critically, in an explosion Friday morning in an eastern county, the SBI said.Jimmy Tyndall, 33, is in custody, Sampson County Sheriff Jimmy Thornton told reporters. The explosives had been found in a car Tyndall was driving and at his residence, Thornton said.Agents Timothy Luper and Brian Joy had been called in to help after Sampson County deputies found homemade bombs and bomb-making materials in a search after a traffic stop Thursday afternoon. The explosion happened as the agents were working to dispose of the material, the SBI said in a statement.Deputies on Thursday stopped Tyndall's vehicle and found pipe bombs during a search, Thornton said. The sheriff said he thought the driver had been stopped for speeding, but then the officers noticed the explosives."Once they began looking, the devices were readily seen," Thornton said. "At that point, then everybody backed away and did nothing else until the SBI bomb squad arrived."Two bombs were found in the vehicle. That led to a search of Tyndall's residence, where three more were found, according to Thornton."I don't think his (Tyndall's) intention was to blow anything up," Thornton said. "I think it was just one of those things he got off on."Joy was airlifted to a burn center in Chapel Hill for treatment and is in critical condition, the SBI said.Officials on Friday said state and federal agents were at the residence to investigate and dispose of any bomb-making materials. "As a result, explosions may be heard during this time," the SBI said. 1630

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
