NASHVILLE (AP) — A Tennessee man who harassed two teenage Muslim girls and then swung a knife and attacked their father has pleaded guilty to a federal hate crime.

Christopher Beckham, 35, of Nashville, appeared in court last week to enter the plea, the Justice Department said Monday in a statement. Beckham pleaded guilty to violating the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act, the statement said.

Beckham admitted that he confronted two sisters in hijabs after they got off a school bus in 2017, saying "Allahu Akbar!" and "Go back to your country!" the statement said. When their father arrived to pick them up, Beckham injured him by swinging a knife and punching at him, and when their mother arrived with another child in a car, Beckham, his knife still drawn, chased after them as well, the Justice Department said.

After police took Beckham into custody, he called the family "terrorists" and vowed to kill them when he got out of jail, the agency added.

Beckham agreed to plead guilty after his federal trial in September 2019 ended with a hung jury. He remains free pending his sentencing, now scheduled for Oct. 7.

"The cowardly and unprovoked attack and display of hate-filled aggression by this defendant toward two innocent young girls and their father is despicable," Acting U.S. Attorney Mary Jane Stewart said. "An attack upon the free exercise of any person's religious beliefs is an attack on that person's civil rights. The Department of Justice will continue to vigorously prosecute such violent acts motivated by hate."
