He defended his parents for their alleged involvement in college admissions scandal, but now blunt-smoking wannabe rapper is arrested for assaulting his father

Police arrested the blunt-smoking son of a wealthy New York couple after he allegedly attacked his father with a ruler, the New York Post reported.

Malcolm Abbott gained notoriety earlier this year when he defended his parents for their part in the high-profile college admissions scandal while he smoked pot outside the family's Fifth Avenue home.

The wannabe rapper, who goes by "Billa," allegedly assaulted his 68-year-old father, Gregory Abbott, on Sunday inside the family's home. Malcolm Abbott is accused of pushing, biting, kicking, and smacking his dad with a ruler, police told the New York Post.

Authorities arrested Malcolm Abbott Tuesday and charged him with felony assault.

Gregory Abbott is the founder and CEO of International Dispensing Corp.

What's the backstory?

In March, Malcolm Abbott described the bribery scandal and federal charges against his parents as being blown "out of proportion."

"They're blowing this whole thing out of proportion," he told The Post in between drags from the blunt. "I believe everyone has a right to go to college, man."

Then, the wannabe rapper, who admitted he didn't go to college, shamelessly plugged his five-track CD.

"Check out my CD, 'Cheese and Crackers,'" Malcolm told the newspaper about the album, which features a song titled, "If I Lost My Money."

What else?

Gregory and his wife Marcia Abbott, 59, on Wednesday, pleaded guilty to paying $125,000 to William "Rick" Singer to have their daughter's ACT and SAT exam scores boosted, according to court documents, USA Today reported.

It's unclear which universities the couple's daughter applied to or ended up attending.

The couple is expected to appear for sentencing Oct. 8. Each faces one year and a day in prison.
