Tom Vilsack yesterday challenged Barack Obama to a debate in his home state of Iowa.
Vilsack will be attending the candidate's forum in Carson City, Nevada, on February 21. However, Barack Obama has decided not to attend the forum, saying that he will be campaigning in Iowa.
The forum in Carson City is being organised by the American Federation of State, County and Municipal Employees, (AFSCME), and all of the other declared candidates have agreed to participate.
Vilsack has said that the AFSCME represents workers in Iowa as well, and they would be happy to organise another forum for the debate. Vilsack has offered to fly out to Iowa after the Nevada forum to meet Obama for a debate.
Obama's campaign have thus far refused the offer.
