The program began in 2013 when Democrats controlled the Legislature, but Republicans forced a reduction in spending after they took control of the state Senate in 2014.
That move forced the state to reduce the number of DMVs supporting the program from 5 to 3. Protestors Monday said that has led to long waits that have made the licenses essentially inaccessible.
The rally marked the launch of "I Drive Colorado"--a coalition of pro-immigrant organizations asking Colorado's Joint Budget Committee to restore funding to the program.
They also point out that fees paid by undocumented immigrants would cover the cost of issuing the licenses.
