SAN ANTONIO -

KSAT 12 has a look back at a 1999 interview of Julian and Joaquin Castro before they began their political careers.

On Tuesday, San Antonio Mayor Julian Castro will give the keynote address at the Democratic National Convention after an introduction by his twin brother Joaquin Castro.

They have come a long way since their days at Jefferson High School. But their potential as city and state leaders was seen early on in their lives.

While both were attending law school at Harvard University, they were guests on a local public access program "SA Community Pride" hosted by Delia A. Guajardo.

"They talked about education and it seems like everything was falling into place to now," said Guajardo, recalling the interview which aired on June 6, 1999.

During part of the interview Guajardo suggests that one of the brothers will be mayor of San Antonio and the other the President of the United States.

She's not bragging about hitting one prediction and said all the credit goes to them.

"There is something about them so special and unique in their leadership," she said. "They're still with us at this level as a community. They understand us and they love San Antonio."

The 1999 broadcast will re-air this Tuesday at 8:30 a.m. and 8:30 p.m. on Time Warner channel 20, U-Verse channel 99 and channel 19 on Grande.
