McClain, a trusted adviser to the speaker Michael J Madigan, is a former lawmaker and Quincy attorney who retired as a high-profile lobbyist from the utility in 2016 but continued collecting six-figure payments from the company. Federal agents raided McClain’s home in Quincy in May 2019, which turned out to be the same month ComEd said they had stopped paying him. The Tribune exclusively reported in November that authorities secretly recorded McClain’s phone calls. Among McClain’s past longtime lobbying clients in addition to ComEd was Walgreens.
