A married-with-children Oklahoma senator who was a leader in President Donald Trump's primary campaign faces prostitution charges after he was found in a motel room that reeked of 'raw marijuana' with a teenage boy that he offered money for 'sexual stuff', police said.

State Senator Ralph Shortey, 35, who deleted a picture of himself and Donald Trump Jr from his Facebook page shortly after news of his arrest broke, is an avowed supporter of the president and served as his Oklahoma state chair in the primaries.

Shortey and the unidentified teenager were found together at a Super 8 Motel in Moore, Oklahoma, around 1am on March 9, after an anonymous tip was made to police requesting a welfare check.

Shortey and the teenager, who is 16 or 17 years old, admitted to police they had engaged in electronic conversations 'pertaining to sexual activities in exchange for money', according to a court affidavit.

The age of consent in Oklahoma is 16.

Their text messages, going back nearly a year, were recorded on the teenager's Kindle tablet that was confiscated as evidence, police said.

Police became involved after being called by the boy's father, who had been contacted by his son's girlfriend, NewsOK reports.

The unidentified girl told police that her boyfriend had said he was 'going to get paid tonight', and she feared he might be 'involved in illegal drugs'.

So, she told police she watched him get into a white Jeep Grand Cherokee with a man and followed them to the Super 8 Motel.

Police said the boy was known to solicit himself sexually on Craigslist and had a history of drug abuse.

When police arrived at the motel, Shortey told them he was alone in the room, but the teenager eventually came out after officers said they were going to enter with a master key from management.

After confronting them in the room that reportedly smelled of marijuana, police found lotion and an open pack of condoms in a backpack.

Shortey had rented the room for one night on March 8, a front-desk manager said.

'It says two adults registered,' the manager added.

While Shortey has not been arrested, he was suspended by the state Wednesday for disorderly behavior and has been stripped of practically all of his political privileges.

Cleveland County District Attorney Greg Mashburn said he is awaiting the investigator's final report before pursuing criminal charges.

Shortey may be facing three charges: soliciting prostitution of a minor, prostitution within 1,000 feet of a church and transporting for the purpose of prostitution.

The Republican from Oklahoma City was first elected in 2010.

Oklahoma GOP Chairperson Pam Pollard said in a statement: 'We condemn the actions of Senator Ralph Shortey to the strongest degree.

'While we believe in the right to a fair trial and that all people deserve their day in court, the accusations against Ralph Shortey are in no way in line with the principles of the Oklahoma Republican Party.'

Earlier this year Shortey advised former state Representative Dan Kirby during a sexual harassment scandal. Kirby later resigned.

Shortey has been married to his high school sweetheart, Jennifer, since 2002. They have two children.

Before beginning his political career, Shortey attended Heartland Baptist Bible College in Oklahoma City in preparation for mission work in Uganda.
