Former Governor John Hickenlooper will be on the Metropolitan State University of Denver campus today. His appearance is the first in a series of student-moderated conversations with each of the state's U.S. Senate candidates. All of them have been invited to participate in the coming months. Hickenlooper's appearance is set for this afternoon. He's among a number of Democrats in the running for the nomination to go up against current Senator Cory Gardner in 2020.
