Martin Shkreli is a free man. Shkreli walked out of prison a free man on Wednesday, May 18, and into a halfway house where he will be on home confinement until September 14.

A friend picked Shkreli up from prison in Pennsylvania on Wednesday.

"Picked up this guy hitchhiking. Says he's famous," he tweeted.

The so-called "Pharma Bro" was once the most hated man in America.

Shkreli got the attention of the Federal Trade Commission (FTC) when he hiked the price of a life-saving AIDS drug by 5,000%.

After a federal investigation into his former company in 2017, Shkreli was sentenced to serve 7 years in prison for securities fraud.

A judge revoked his $5 million bond when he threatened Hillary Clinton while appealing his conviction.

While in prison, Shkreli agreed to pay $40 million to consumers to settle the price gouging allegations.

He was also ordered to pay $64.6 million he earned in profit from the price hike. And he is banned from ever working in the pharmaceutical industry again.
