Some Republicans say federal agencies that recently cut ties with ACORN — the Association of Community Organizations for Reform Now — should also consider severing their relationship with the Service Employees International Union. The SEIU and ACORN have long worked closely together, with the union paying the association more than $3.6 million in the past three years and sharing some office locations and leaders with the group. ACORN also faces attention from the Democratic attorney general of Louisiana, who filed a subpoena Monday in Baton Rouge that suggested $5 million may have been embezzled from the group, five times what ACORN has acknowledged. James “Buddy” Caldwell cited an ACORN internal review shared with board members for his information, which was first reported by the New Orleans Times-Picayune.
