Civil rights summit opens with immigration talk

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

Castro was among the first speakers Tuesday at the Lyndon B. Johnson Presidential Library in Austin. The library is holding a three-day summit to mark the 50th anniversary of the Civil Rights Act.

President Barack Obama is giving the keynote address Thursday. Castro is a top Obama surrogate but says he's uncomfortable with the number of deportations during his administration.

Castro and former Republican Mississippi Gov. Haley Barbour say it's important that Congress sets realistic standards for border security.

Former President George W. Bush is scheduled to be the summit's final speaker Thursday.
