Biden heckled by Parkland father during event to celebrate new gun law.

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.“We have to do more than that!” Oliver shouted, among other remarks,

while standing up and wearing dark sunglasses, grey beard and purple jacket.

At first Biden told him, “Sit down, you’ll hear what I have to say,” but then the president relented and said,

“Let him talk, let him talk, OK?” By then, however, security had already stepped in to take Oliver away.
