Mark Kirk and Tammy Duckworth faced off in their first debate Monday.
The two U.S. senate candidates criticized their own political party’s nominees for president.
Duckworth, a Democratic U.S. Representative, responded to an inquiry about Hillary Clinton’s private email server.
"She needed to turn over those emails," Duckworth said. "We needed to make sure that things were more transparent. I do have real concerns."
Incumbent Republican Sen. Mark Kirk commented on Donald Trump’s 1995 tax returns, which were recently leaked to the New York Times.
