Anthem fought back against an Obama administration antitrust lawsuit on Wednesday by conditioning its expansion in the struggling Obamacare market to approval of its acquisition of Cigna. The company plans to add nine states to its Obamacare participation if the deal goes through, company officials said on a call with investors. Last week, the Department of Justice sued to block Anthem’s proposed $54 billion acquisition of Cigna and also filed suit against Aetna’s planned $37 billion takeover of Humana.
