Clay Siegall, co-founder and CEO of Seagen, has resigned in the wake of his arrest on charges of domestic assault, the company said Monday.
Siegall, 61, was arrested April 23 after police said he repeatedly shoved his wife to the ground during a late-night dispute, resulting in bruises and abrasions. He has been on a leave of absence since May 5, according to Seagen, which is conducting an investigation into his conduct. Siegall told police he did not assault his wife.
