President Trump on Tuesday said he has a call scheduled with Russian President Vladimir Putin to discuss a possible case of plague at a Siberian research institute. Speaking to reporters at the White House, Trump said he would be talking with Putin about the case "very soon," the AP reports. Health authorities are investigating after the death of an employee at an anti-plague institute, which authorities attributed to pneumonia with an unknown cause. Asked what the US intelligence community was saying about the case, Trump said the US is in "very deep discussions" on the topic. "We'll be able to report about it, probably tomorrow," Trump said.
