Frank Stallone, younger brother of Sylvester Stallone, apologized via Twitter on Sunday for a profanity-laced rant mocking one of the Marjory Stoneman Douglas High School shooting survivors.
The apology came a day after the musician verbally attacked MSD student David Hogg in a since-deleted tweet.
"This David Hogg (expletive) is getting a little big for his britches," Frank Stallone wrote. "I'm sure someone from his age group is dying to sucker punch this rich little (expletive). Watch him run home like the coward he is. He's the worst rep for today's youth headline grabbing punk."
The apology said as follows:
Hogg recently made headlines after conservative Fox News host Laura Ingraham mocked the Parkland school shooting survivor after he revealed that he had been rejected from several prominent California colleges, including UCLA.
Hogg then called for an advertising boycott of Ingraham's show.
Frank Stallone posted that he was making his Twitter account private after the backlash, but it was made public again when he issued his apology.
