During a ceremony at the White House touting the signing of a new gun law, President Joe Biden was interrupted by the father of a Parkland school shooting victim.
Manuel Oliver, who lost his son Joaquin in 2018 during the shooting at Marjory Stoneman Douglas high school in Parkland, Florida, was among the families of past mass shooting victims invited to the White House for Monday's event. As Biden spoke, Oliver stood up and began to heckle him.
