At the beginning of his rally in Corpus Christi, Texas, Senator Barack Obama recognized the Dallas police officer who died in the line of duty while providing escort service for Senator Hillary Clinton’s motorcade this morning.

Obama explained to the crowd that he, Clinton, and Senator John McCain all get help from local law enforcement to set up motorcades and ease traffic while campaigning. “One of the members of Senator Clinton’s detail got into an accident and passed away. He actually helped me when we were in Dallas,” Obama said, referring to a rally he held in Dallas just two days ago, where he relied on the Dallas Police Department for help getting to and from the airport.

“His name was Victor Lozada-Tirado. And so if everybody will just observe a brief moment of silence for him and his family, let ‘em know that our thoughts and prayers are with them,” he said. The thousands gathered in the Corpus Christi arena were still for about 10 seconds.

“It’s a reminder of the outstanding work that law enforcement does for us each and every day and so I hope that everybody can give a big round of applause for our law enforcement officers,” Obama said, before he began his stump speech.
