Also her leftist tie was derived from her marriage to a Chinese man:
"""
Howe met his wife, a white woman named Sanora Babb, before World War II. They traveled to Paris in 1937 to marry, but their marriage was not recognized by the state of California until 1948, after the law banning interracial marriage was abolished.[5][13] Due to the ban, the "morals clause" in Howe's studio contracts prohibited him from publicly acknowledging his marriage to Babb. They would not cohabit due to his traditional Chinese views, so they had separate apartments in the same building.[14]
During the early years of the House Un-American Activities Committee hearings, Babb was blacklisted due to supposedly having Communist ties from her marriage to Howe; she moved to Mexico City to protect the "graylisted" Howe from racial harassment.[5][15]
Howe raised his godson, producer and director Martin Fong after Fong arrived in the United States.
