In his farewell letter, Bob Dole cracked a joke about voter fraud in Chicago

While speaking at her father's funeral service in Washington D.C. on Friday, Bob Dole's daughter Robin Dole read from part of a farewell letter that she said her father had written with a former staff member.

Dole, who passed away on Sunday at the age of 98-years-old, slipped a joke about voter fraud into the letter.

"As I make the final walk on my life's journey, I do so without fear because I know that I will again not be walking alone. I know that God will be walking with me. I also confess that I'm a bit curious to learn if I am correct in thinking that heaven ... will look a lot like Kansas, and to see, like others who have gone before me, if I will still be able to vote in Chicago," Dole's daughter read from her late father's letter.

Dole, a World War II veteran who was seriously wounded while serving, asked people to visit the WWII memorial and other veterans memorials around the nation.

"I do have one request to make of you," Dole said in the letter. He noted that since the 2004 dedication, "it has been my honor to go as often as I could, to the World War II memorial here in Washington D.C. to welcome and thank the World War II veterans and all veterans who are visiting there. Since I won't be making that visit anymore, I hope that you will, and that you will ask your children and grandchildren to visit veterans memorials across America, and to never forget the sacrifice made not just by my generation, but by all those who wear the uniform of our country."

"My final words are the exact ones that Dwight Eisenhower used to conclude his speech ... nearly seven decades ago. I believe in the future of the United States of America," the letter stated.

Dole had a lengthy political career that included service in the U.S. House and Senate. As the Republican presidential nominee during the 1996 election, he ultimately lost to incumbent Democratic President Bill Clinton.
