Ashton Kutcher resigns from anti-child trafficking nonprofit over Danny Masterson character letter

Actor Ashton Kutcher has stepped down as board chair of an anti-child trafficking group that he co-founded in the wake of criticism he received over a letter of support he penned on behalf of his former "That '70s Show" co-star Danny Masterson following Masterson's criminal conviction for raping two women.

In a resignation letter posted on the website of the group Thorn, Kutcher wrote that he "cannot allow my error in judgment to distract from our efforts and the children we serve."

In June, the 43-year-old Masterson was found guilty of raping two women at his Hollywood Hills home in the early 2000s.
