Alicia Garza, co-founder of Black Lives Matter, revealed that she was recently identified as a potential target of white supremacist groups. Sharing the terrifying developments on Twitter, Garza said the Federal Bureau of Investigation spoke to her on Friday and identified an Idaho man who plotted to attack the activist.

“The FBI visited my house today. They arrested a man in Idaho on weapons charges who they believe was affiliated with white supremacist groups,” Garza tweeted. “They found my name on a list in his home, alongside others.”
