FBI agents on Thursday raided the Cleveland offices of the Ohio Organizing Collaborative, a pro-democracy organization that helps register voters in that state, three people briefed on the search told MS NOW.

Agents also fanned out across the state, showing up at the homes of the group’s leaders and staff members, carrying some subpoenas and seeking information and electronic devices, according to the three people briefed, two of whom spoke on the condition of anonymity to discuss a sensitive ongoing investigation. Members of the group contacted lawyers on Thursday to determine their legal options, the people said.

Prentiss Haney, a board member of the Ohio Organizing Collaborative, told MS NOW Thursday night that agents approached people with connections to the group, including some who had performed basic canvassing and volunteer work, and pressed them for information.

Agents were “basically trying to fish for information,” Haney said.
