A federal jury found Michael Madigan’s former chief of staff guilty of perjury and obstruction of justice charges on Thursday, convicting him of lying to a grand jury to protect his former boss.
Tim Mapes, 68, served for years under former Democratic Illinois House Speaker Madigan as the clerk of the Illinois House and as Madigan’s chief of staff.
In May 2021, federal prosecutors charged Mapes with lying to a grand jury in a federal probe connected to the longtime former speaker.
