Bieber accused Laura Ingraham of “disrespecting” the rapper after she seemingly laughed while introducing a segment about the musician, who was shot dead in Los Angeles last month.
Ingraham referred to Hussle as “this dear artist” and took aim at him after his 2016 hit ‘FDT’ featured the chorus “Fuck Donald Trump”.
She asked: “The chorus that goes on and on, is that related to lowest unemployment ever, basically, for African-Americans?”
Responding on Instagram, Bieber described her behaviour as “absolutely sickening.”
Bieber said: “Laura Ingraham absolutely disgusting what you did on national television. How dare you laugh in the face of a person who has passed on.
“Doesn’t matter who it is. But disrespecting someone’s who was a pillar in the community and did right by people?
“Did you not think about the family who just lost a love one and now have to see you mock him on national television It’s absurd and you should be fired period. #repost#spreadawareness.”
Bieber’s remarks come after Ingraham was previously criticised by Snoop Dogg and The Game, who both called for her to be fired.
This comes after a suspect was charged in Hussle’s killing. Eric Holder, 29, is now facing life in prison after prosecutors charged him with one count of murder and two counts of attempted murder.
A memorial service to the rapper was held last week – with the likes of Stevie Wonder and Barack Obama all paying tribute to the late star.
