The House Oversight Committee demanded access to internal documents from the Federal Emergency Management Agency for its investigation into allegations of bias against Donald Trump voters.

Following a high-profile hearing before the committee on Tuesday, committee members are pressing FEMA administrator Deanne Criswell to provide information that could determine whether the agency discriminated against certain properties displaying Trump campaign signs. The hearing came after testimony from whistleblowers inside the agency indicated they were instructed to skip those houses while seeking to offer disaster relief from devastating hurricanes.
