(CNN)-- It could be even harder to sign-up for the Affordable Care Act this fall.
More than 8 in 10 groups that help people enroll for the ACA say they're getting less federal funding from the Trump administration.
That's according to a new report from the Kaiser Family Foundation, a non-partisan research organization.
The Trump administration announced late August that it would reduce their funding by 41%.
The groups received a total of $37-million for the upcoming open enrollment season, which runs November 1st through December 15th.
The Trump administration is also slashing advertising by 90%, and they're taking the federal exchange offline for maintenance more often than in prior years.
Critics say these moves will undermine sign-ups.
The Kaiser survey says despite the funding cuts, most groups will continue to operate in 2018, but nearly all expect to lay off staff, reduce their advertising and curtail their outreach programs.
