HOUSTON -- The latest batch of e-mails from the District Attorney's county computer includes some shocking videos, personal messages and jokes, KPRC Local 2 reported Tuesday.

One of messages was a racial joke about President Bill Clinton, attributed to a Canadian TV show, forwarded by Chuck Rosenthal to his friend Dr. Sam Siegler.

"The closest thing we ever had to having a black man as president," the e-mail read. "Number 1 - He played the sax. Number 2 - He smoked weed. Number 3 - He had his way with ugly white women. Even now? Look at him… his wife works, and he doesn't! And, he gets a check from the government each month."

Rosenthal was unavailable for comment. KPRC Local 2 also unable to contact Siegler, but his wife talked.

Siegler's wife is prosecutor Kelly Siegler, one of four Republican candidates running in the primary to replace Rosenthal. She won the top spot on the party's ballot on Tuesday.

"I haven't seen them to know if they offensive to people or not," Kelly Siegler said. "My husband cusses like a sailor. He has crude humor to put it mildly. I have no idea what all jokes he sends or receives all day. I can just say he's self-employed. It's his computer. It's his office. It's his time."

The e-mail files also contained racy videos and photos, some of which were pornographic. It is unclear who sent them.

The chairman of the Harris County Republican Party said he thinks Rosenthal should step down.

"He needs to resign," Jared Woodfill said. "It's past pulling his name off the ballot now. He needs to resign."

The e-mails were subpoenaed in a police brutality case against the Harris County Sheriff's Office. Lloyd Kelley, one of the attorneys in that case, said some of the e-mails showed criminal conduct by Rosenthal. Kelley said he wants a special prosecutor appointed to investigate.
