AUSTIN, Texas (AP) — A civil rights summit headlined by four of the five living U.S. presidents has started with a top Republican and Democrat finding common ground on ideas for immigration reform.

The Lyndon B. Johnson Presidential Library in Austin is holding a three-day summit to mark the 50th anniversary of the Civil Rights Act.

San Antonio Mayor Julian Castro and former Republican Mississippi Gov. Haley Barbour were among the first speakers Tuesday. Both say it's important that Congress sets realistic standards for border security.

Castro is a top supporter of President Barack Obama but says he's uncomfortable with the number of deportations during Obama's administration.

Obama is giving the keynote address Thursday, and former President George W. Bush is scheduled to be the summit's final speaker Thursday.
