Massie is stepping aside to run for Superintendent of Public Instruction. He had held the seat since 1998.
The event began at 1 p.m. with Rothfuss annoucing his candidacy and goals for Laramie and Wyoming.
After the announcement, Laramie residents were able to visit with Rothfuss and ask him their questions. Many students, staff, faculty and community members stopped by to enjoy coffee and cookies, and to share their concerns with Rothfuss, asking about his ideas on energy development and the funding of the university.
"This was a perfect opportunity for Chris to share with Laramie residents what he can do for Laramie and for the state of Wyoming as a senator for district nine," said Simons. "We're looking forward to getting out there and sharing our ideas with the voters and listening to their concerns."
