PORTLAND, Texas (AP) — Hillary Adams says that until last week, only a couple of close friends knew about the savage beating she received seven years ago from her father, a Texas judge who handles child abuse cases.

Now the beating is on display to the world on YouTube thanks to a secret video she made, and her father, Aransas County Court-at-Law Judge William Adams, is the subject of a police investigation.

Hillary Adams, 23, says the outpouring of support and encouragement she's received since posting the 2004 video online last week is tempered by the sadness that it's her father lashing her 17 times with a belt and threatening to beat her "into submission." The 8-minute video had been watched nearly 2 million times by Thursday morning.

"I'm experiencing some regret because I just pulled the covers off my own father's misbehavior after so many people thought he was such a good person. ... But so many people are also telling me I did the right thing," she told The Associated Press outside her mother's home in the Gulf Coast town of Portland, near Corpus Christi.

"He's supposed to be a judge who exercises fit judgment," she said.

And she said the videoed attack was not a one-off. "It did happen regularly for a period of time," she told NBC's "Today" show on Thursday.

In the same interview, Hallie Adams blamed her ex-husband's bouts of violence on his "addiction," calling it a "family secret." She did not elaborate. Their 22-year marriage ended in 2007.

The judge did not return an AP reporter's call seeking comment early Thursday.

Police in Rockport, where the 51-year-old judge lives, opened an investigation Wednesday after receiving calls from several concerned citizens, Police Chief Tim Jayroe said.

William Adams has been receiving threatening phone calls and faxes at the courthouse since the video went online, Aransas County Sheriff Bill Mills said.

No one answered the door Wednesday at the judge's home, repeated calls to his office rang unanswered and his attorney, William Dudley, did not respond to phone messages seeking comment. A neighbor said she saw Adams and his girlfriend packing luggage, a briefcase and rifles into their truck.

Corpus Christi television station KZTV caught up with the judge while he was getting into his vehicle Wednesday, and he confirmed it was him in the video. But he said it "looks worse than it is" and that he doesn't expect to be disciplined.

"In my mind, I haven't done anything wrong other than discipline my child after she was caught stealing," Adams said. "And I did lose my temper, but I've since apologized."

When told of her father's comments, Hillary Adams said, "it's a shining perfect example of his personality and he believes he can do no wrong. ... He will cover up rather than admit to what he did and try to come clean."

She stressed that she did not post the video as revenge and does not want her father punished. Rather, she did it because she thinks it will force him to seek help, and because he has been harassing her and she thought posting the clip would make that stop.

"We need to reach out to victims and the abusers themselves to get people to realize what it actually is," she said.

Hillary, who was 16 at the time, said she secretly videotaped the beating in her bedroom because she "knew something was about to happen." She says her parents were angry at her for using her computer to download pirated content over the Internet.

In the clip's opening seconds, William Adams is heard telling Hillary's mother, "Go get the belt. The big one. I'm going to spank her now." With belt in hand, he turns off the light and tries forcing his daughter to bend over the bed to be beaten, but she refuses.

"Lay down or I'll spank you in your (expletive) face," Adams screams while he lashes her with sweeping blows across the legs, ignoring her wails and pleas for him to stop.

A few minutes into the video, Hillary's mother barks at her to "turn over like a 16-year-old and take it! Like a grown woman!" For about a minute, the ordeal appears to have ended after both parents leave the room and shut the door. But the judge then storms back into the room and the beating resumes.

Hallie Adams said she was "completely brainwashed and controlled" by her ex-husband.

"I did every single thing that he did," she told NBC. Hillary Adams said she is not angry at her mother.

Child advocates roundly condemned the beating as abuse. But investigators may decide that the judge's actions, while shocking, weren't criminal.

The lines between what's deemed child abuse and what's considered an acceptable level of discipline differ across the country and among various social groups, though the use of objects such as belts and sticks is usually seen as beyond any normal physical punishment, said David Finkelhor, a University of New Hampshire sociology professor who heads the school's Crimes against Children Research Center.

Adams, Aransas County's top judge, was elected in 2001 and has dealt with at least 349 family law cases in the past year alone, nearly 50 of which involved state caseworkers seeking determine whether parents were fit to raise their children.

Patrick Crimmins, a spokesman for the state Department of Family and Protective Services, said in an email that the agency is aware of the video and "will take the appropriate steps in this matter." He said the agency would have no further comment.
