WATCH: Gov. Walker's budget proposal coming into focus, budget plan unveiled Tuesday

MADISON (AP) — Gov. Scott Walker's state budget proposal is coming into clearer focus, with the second term Republican revealing major portions including $300 million in cuts to the University of Wisconsin System and no new taxes to pay for transportation projects. But much also remains unknown before Walker is to release his two-year spending plan to the Legislature.

Meanwhile, Democrats are speaking out against various parts of Gov. Scott Walker's budget the day before the Republican releases his entire plan to the Legislature.

Democrats on Monday say what is known so far about Walker's plan would not create opportunities for people to succeed in Wisconsin. They say Walker is crafting his budget to appeal nationally as he looks ahead to a possible presidential run.

Democrats are taking particular aim at Walker's call to cut the University of Wisconsin System funding by 13 percent, or $300 million, borrowing more than $1 billion for roads projects and requiring drug tests for public aid recipients.

Democrats are calling for raising the minimum wage, accepting federal Medicaid money and restoring cuts Walker and Republicans made to public schools.

Walker will deliver the budget Tuesday night.
