President Donald Trump met with major health insurers Monday morning, in the midst of intensifying public pressure to preserve the law and political divisions over how to best dismantle and replace former President Barack Obama’s signature domestic policy achievement, the Affordable Care Act. The meeting included leaders from Blue Cross Blue Shield, Cigna, Humana, UnitedHealth Group, Aetna, Anthem, Kaiser Permanente and the industry lobbying group, America’s Health Insurance Plans.
