The estranged wife of Sean Parnell, the Republican endorsed by former President Donald Trump for U.S. Senate in Pennsylvania, testified under oath Monday that she endured years of rage and abuse from him, including being choked until she had to bite him, a newspaper reported.

Laurie Parnell's testimony came during divorce and custody proceedings in Butler County court over the custody of their three school-age children, the Philadelphia Inquirer reported.

In their suburban Pittsburgh home, the family was "walking on eggshells. The minute he walked back into the house we were petrified," she testified.
