Family of late boxer Jack Johnson asks for pardon from President Obama

Jack Johnson was accused of Mann Act in 1913

HOUSTON - Relatives and hometown supporters of boxing's first black heavyweight champion are turning to YouTube to convince the president to posthumously pardon him of a 1913 conviction for accompanying a white woman across state lines.

Jack Johnson was convicted of the Mann Act by an all-white jury under the Jim Crow-era law and sentenced to a year in prison.

Lawmakers have sent the president a resolution asking for a pardon three times in the last decade, most recently in March.

His great-great niece, Linda Haywood, says in the new video that her family was ashamed Johnson had been railroaded and went to prison. She says he had to sneak around with his white girlfriend and later wife "because of the times that they lived in."

The video was made in Galveston, Johnson's hometown in Texas.
