On a 911 tape released by authorities, Angela Bryant is heard saying that she wanted to "put an end to it."
"I can't keep letting him do this," she said on the tape.
Angela Bryant has since submitted an affidavit asking prosecutors not to pursue the case. Family violence is a misdemeanor punishable by up to a year in jail and a $4,000 fine.
Bryant sat next to his mother at a press conference that lasted about 2 minutes. Neither spoke or took questions.
"I would love to make a statement, but I can't," Dez Bryant said as he left. "I can't."
Instead, West read a statement calling any dispute "a family matter that can be worked out through counseling."
"They ask that there not be a rush to judgment concerning their family," West said.
Prosecutors have not announced whether they will pursue charges against Bryant and declined comment Tuesday. The NFL and the Cowboys declined to comment.
