IOWA CITY, Iowa (AP) – University of Iowa President Sally Mason says she plans to retire after leading the school since 2007.  Mason announced Thursday that she will step down Aug. 1 after managing a devastating flood, major budget challenges and numerous controversies.

The 64-year-old biology professor came to Iowa City from Purdue University, where she had been provost. Almost immediately, she was thrown into managing one problem after another, many caused by events outside her control. A historic June 2008 flood came to symbolize her tenure, when heavy rains caused the Iowa River to overflow its banks and damage and destroy numerous buildings.

Mason worked to keep the university open and spent the following years overseeing hundreds of millions of dollars of rebuilding projects.

DES MOINES, Iowa (AP) – A group trying to draft Sen. Elizabeth Warren into the 2016 presidential race has hired several staffers in Iowa.  The “Run Warren Run” campaign announced Thursday that it had opened an office in Des Moines and hired an Iowa field director and four other field organizers in the early-voting state. The field director is Blair Lawton, an Iowa native who worked for President Barack Obama’s 2012 Iowa campaign.

The campaign is being organized by MoveOn.org and Democracy for America. They held their first Iowa meeting in Des Moines last month. The activists are trying to persuade Warren to seek the Democratic nomination in 2016, but the Massachusetts senator has said she isn’t running.

MoveOn plans to spend $1 million on its Warren effort and Democracy for America has pledged $250,000.
