Good afternoon, Chicago.
Illinois U.S. Reps. Sean Casten and Jesús “Chuy” García added their names to the growing list of Democrats calling for President Joe Biden to step aside and not run for a second term.
Casten and García become the fourth and fifth Illinois congressional Democrats to encourage the 81-year-old Biden to abandon his effort to defeat former President Donald Trump in the November election. Trump accepted the Republican presidential nomination Thursday night in Milwaukee.
In a submitted opinion piece published online Friday in the Tribune’s opinion section, Casten, a west suburban congressman since 2019, said if the upcoming election was a referendum on performance, promises and character, he thinks Biden would defeat Trump.
