It is the application of the parts of these regarding material support. Many groups, including the ACLU, the Leadership Conference on Civil Rights and religious organizations opposed Real ID because of these and other onerous provisions.
It looks like they are attempting to change some of these provisions. Better, I think, would be to repeal them.
Here's some info from January 2007:

A Colombian woman who was kidnapped, assaulted and forced to give medical care to guerrilla groups at gunpoint is among those whose asylum claims were rejected on material-support grounds, as is a Sri Lankan man who was kidnapped by the Tamil Tigers and paid his own ransom.
On Thursday, officials from the Departments of Justice, State and Homeland Security announced a series of changes to the material-support policy, including the expanded use of waivers to allow entry to groups that would otherwise be banned.
Paul Rosenzweig, assistant secretary for international affairs at the Department of Homeland Security, said the changes were the result of concern over the "unintended consequences" of the material-support provisions, which are part of the Patriot Act and Real ID Act.
