Advocates representing more than 90 disability organizations are expected to amass on Capitol Hill Wednesday to show support for Medicaid.

The noon rally on the west side of the Capitol, is expected to draw more than 1,000 people with disabilities and their allies from across the nation.

The action comes as advocates are increasingly worried that significant changes to Medicaid could be on the horizon.

Currently, a Congressional “super committee” made up of a bipartisan group of a dozen lawmakers is working to identify spending cuts ahead of a November deadline in an effort to lower the federal debt. Medicaid and other entitlement programs are likely to be on the table.

Meanwhile, President Barack Obama laid out a plan on Monday to make what he called “modest adjustments” to the government health program.

“Medicaid is the national safety net for millions of people,” said Bob Kafka, a Texas organizer with ADAPT, a disability self-advocacy group that’s behind the rally. “The federal budget debate has largely overlooked the real impact of severe Medicaid cutbacks… We will be in the nation’s capital to be heard in force, to let decision-makers know that real budget reform means recognizing that Medicaid matters.”

In addition to the event in Washington, local rallies are also planned in a handful of states.
