Kansas lawmakers face security concerns amid contentious hearings on vaccines and drugs.

Frustrations flared during an anti-vaccine hearing in Kansas, with a witness making a perceived threat towards a senator, prompting the senator to request security and eventually leave the meeting. The bill being discussed would weaken vaccination requirements in workplaces, schools, and day cares. The tension comes as Kansas Legislature committees enter crunch time, with some bill hearings facing stricter time limits than usual. The senator opposing anti-vaccine politics believes that more than 90% of her constituents support regularly scheduled vaccinations.
