LOS ANGELES — Frank Stallone is apologizing for a profane tweet attacking a survivor of the Florida school shooting.

Mostly known for being the brother of Sylvester Stallone, the actor and musician backed away from a Saturday tweet attacking teenager David Hogg. Hogg has become a powerful voice for gun control after the attack at Marjorie Stoneman Douglas High in Parkland, Florida.

Stallone used expletives and derogatory terms to refer to Hogg, suggesting one of the teenager's peers must by "dying to sucker punch" him. Stallone later deleted the tweet and one aimed at another Parkland survivor.

Stallone's tweet drew immediate backlash. Prominent Hollywood producer Judd Apatow tweeted a joke at Stallone's expense.

"We don't have to worry about a Frank Stallone boycott," Apatow tweeted. "That started in the late seventies."

It's not the first time a prominent Twitter user has gone after Hogg. Conservative television and radio personality Laura Ingraham tweeted about Hogg's college acceptance prospects earlier this week, causing advertisers to flee her FOX News television show.

And in the immediate aftermath of the Feb. 14 Parkland shooting, a Florida legislative aide accused Hogg and his classmate Emma González of being "actors that travel to various crisis when they happen."

The aide was promptly fired after emailing that accusation to a Tampa Bay Times reporter.

Tampa Bay Times staff writer Kirby Wilson contributed to this report.
