The BBC talked to Andy Parker, father of slain journalist Alison Parker, about gun control in the US.

He urged President Obama to "work the press" on gun control and that he knew it would be an uphill battle, but he could do it.

"Mr President, you need to do this, you need to tackle this, you can do this, I will help you do this and the press is with you because they just lost one of their own."
