Illinois Gov. Pat Quinn will endorse legislation in his State of the State address next week that would raise Illinois' high school dropout age to 18, according to a statement from the Democrat's office.
The proposal would answer a call from fellow Democrat Barack Obama, who in his State of the Union address on Tuesday urged states to keep students in high school long enough for them to get their diploma.
