And in healthcare news, Humana has announced it will stop offering health insurance coverage in the Affordable Care Act’s state marketplaces in 2018—dealing another blow to Obamacare. The announcement came as Aetna said it was abandoning its plan to merge with Humana, after the proposed $37 billion merger was blocked on antitrust grounds. Last year, Aetna announced it would cut its participation in the Affordable Care Act’s marketplaces by two-thirds. President Trump and Republicans have vowed to dismantle the Affordable Care Act.
