Former President Donald Trump joked about his legal challenges while campaigning in eastern Iowa on Tuesday night, just hours after announcing he’d received a target letter in the Justice Department’s investigation into efforts to overturn the 2020 election. Headlining a Republican county meeting, Trump attacked the Justice Department while trying to make light of what could be his third criminal indictment since March. He told the audience at an Elks Lodge in Cedar Rapids: “I didn’t know practically what a subpoena was and grand juries. Now I’m becoming an expert." He continued to cast the cases as politically motivated in an interview later with Fox News host Sean Hannity.
