After all, in April, Aetna chief executive Mark Bertolini had called selling insurance in the exchanges "a good investment." Earlier this month, after Aetna announced in an earnings call this month that it was reevaluating its participation in the exchanges, Sen. Elizabeth Warren (D-Mass.) Aetna would withdraw from many insurance exchanges, limiting its participation to no more than 10 states in 2017, rather than the 20 it had been planning. Later in July, Justice Department officials blocked the merger. Bertolini's letter was also a response to a demand for information from the Justice Department.
