Manuel Oliver shouts ‘we have to do more’ as president gives speech marking measure at White House
Joe Biden has been heckled by the father of a mass shooting victim during a White House event celebrating the passage of a federal gun safety law.
The US president was delivering a speech on the South Lawn on Monday when he was interrupted by Manuel Oliver, whose 17-year-old son, Joaquin, was among 14 students and three staff members killed at a high school in Parkland, Florida, in 2018.
