Madrid, Spain (CNN) President Barack Obama and former President George W. Bush on Tuesday will speak at an interfaith memorial service in Dallas for five police officers slain late last week, as well as meet with the victims' families.

The President will visit the Texas city at the request of Dallas Mayor Mike Rawlings, White House Press Secretary Josh Earnest said in a statement Sunday afternoon. On Sunday evening the White House announced that Bush would join his successor at the memorial service in Texas.

Vice President Joe Biden will also attend the service at the Morton H. Meyerson Symphony Center, as will former first lady Laura Bush.

Obama and Bush are expected to meet with families of the fallen officers. The President is cutting short a European trip to travel to Dallas, but he has spoken out on the shootings several times while abroad. While in Spain Sunday, the President condemned citizens who attack police officers, saying they are performing a "disservice to the cause" of criminal justice reform.

While the joint appearance between Bush and Obama is unusual, such occasions do have precedent. The two men appeared together at Ground Zero on September 2011 for the tenth anniversary of 9/11 and also in Tanzania in 2013 to lay a wreath at the memorial for the 1998 U.S. Embassy bombing in Dar es Salaam.
