A Chicago man who prosecutors said played a key role in a violent mob that broke through a barricade outside the U.S. Capitol on Jan. 6 has been sentenced to more than three years in federal prison.

       The 38-month sentence handed down Wednesday to Daniel Leyden in U.S. District Court in Washington was one of the stiffer terms given to the more than three dozen Illinoisans arrested so far in the Capitol attack.

       Leyden, 55, a South Side electrician who previously worked for the Park District, pleaded guilty along with his brother, Joseph, 56, of La Grange, court records show. Joseph Leyden was sentenced by U.S. District Judge Trevor McFadden on Wednesday to six months behind bars.
