AUSTIN, Texas (AP) — The Lyndon Baines Johnson Presidential Library in Austin is hosting a civil rights summit this week, highlighted by a keynote address by President Barack Obama.

The three-day conference will commemorate the 50th anniversary of the 1964 Civil Rights Act, signed into law by Johnson.

Other scheduled speakers include former Presidents Jimmy Carter, Bill Clinton and George W. Bush. Panel discussions will look back at the civil rights movement and address current topics such as immigration and gay marriage.

LBJ Library Director Mark Updegrove said he hopes the summit will mark a turning point in Johnson's legacy, moving it away from the Vietnam War to the domestic policies Johnson pushed that transformed civil rights.
