Des Moines Register | The Des Moines Register

Twenty Democratic presidential candidates will speak at AARP/Des Moines Register Caucus Forums across Iowa over five days in July, the organizations announced Tuesday.

The forums, moderated by the Register's opinion editor, Kathie Obradovich, and Radio Iowa News Director Kay Henderson, will focus on older Iowans' concerns, many of which are shared by all voters, said Carol Hunter, the Register's executive editor.

"These forums will put candidates on the record, and older voters will be watching," John Hishta, AARP senior vice president of campaigns, said in a statement.

Each candidate will have 25 minutes on stage to answer questions from the moderators and the audience.

The events will be attended in person by 200 to 250 AARP members, who will be selected by invitation only. The Register will livestream the events at DesMoinesRegister.com.

President Donald Trump has also been invited to share his views with AARP members before the 2020 election, the organizations said.
