Portland-based lead-safety activist Tamara Rubin has been asked to leave the nationwide nonprofit she founded and built over the past five years, the Lead Safe America Foundation.

The split has fractured the organization's board. Some are siding with Rubin, the ousted executive director, and disavowing the actions of the board president, treasurer and attorneys; others are urging her to cease the lead activism she's done since discovering her children had lead poisoning in 2005.
