DES MOINES, Iowa (AP) — Jill Biden, the wife of Vice President Joe Biden, will deliver the commencement address at Southwestern Community College in Creston, which was hit by a tornado last weekend. The office of the vice president says Friday that Biden will address graduates on May 11. It’s one of two commencement addresses she’ll give this spring. The other is on May 4 at Broward College in Fort Lauderdale, Fla. Southwestern Community College is a two-year school, which serves over 10,000 students a year. Biden, an educator for more than 30 years, has taught English in community colleges for the past 18 years and currently teaches at a community college in Virginia. An EF2 tornado hit Creston last Saturday, damaging the community college and a hospital.
