He resigned on March 22 after it came to light that he had propositioned a young man and offered to pay him for sex.
Shortey is scheduled to plead guilty on November 30, two weeks before his trial was set to commence on December 5. Still, he will be required to serve at least a 10-year prison term, the mandatory minimum time for child sex trafficking.
"It is in my best interest and in the best interest of my family", Shortey wrote on plea paperwork signed Monday.
The defense attorney, Ed Blau, made a decision to negotiate a plea agreement after looking at all of the evidence.
The federal indictment against Shortey mentions that the former senator, under a fake name, created a Craigslist account where he requested anyone responding to his ads communicate with him via Kik, a social media application that allows users to send photos, videos, and text messages.
Shortey was first elected to the Oklahoma state Senate in 2010.
Shortey has demonstrated a complete lack of ethics, despite the fact that he is constantly promoting "Christian values" and claiming the divine moral high ground.
On March 9, Shortey surrendered to police on charges of engaging in child prostitution, transporting a minor for prostitution and engaging in prostitution within 1,000 feet of a church. She then called his father, and his father notified police, according to News OK.
Police reported Shortey and the victim had carried on a conversation about sex using the messaging app Kik before going to the hotel.
According to The Daily Kos, Shortey's shared a picture of him embracing Donald Trump Jr. on March 10, the day after he was found by police in the motel room with the teenage boy.
"I don't really have any legitimate things I need help with right now", Shortey wrote, according to the indictment.
'Shortey used those pseudonyms nearly exclusively for illicit and illegal sexual interests or encounters, several of which included communications and exchanges of pornography with underage males, and/or the sharing of child pornography, ' an Federal Bureau of Investigation agent wrote in the affidavit, according to News OK. Would you be interested in "sexual" stuff?' police said Shortey asked the teen.
A politician took advantage of a child who needed money. We'll see if the judge agrees.
