The former GOP Minnesota state senator who was arrested last week after allegedly trying to meet a minor for sex is now accused of trying to conceal possible evidence in his case.

Republican Justin Eichorn first made headlines March 17 for co-authoring a state bill that would classify “Trump Derangement Syndrome” as a mental illness, with criteria such as “verbal expressions of intense hostility toward” President Donald Trump. He has since been removed from the bill.

The same day the bill was introduced, Eichorn was taken into custody and charged with soliciting a minor for prostitution after attempting to meet with an undercover agent who was posing as an underaged sex worker, according to a motion filed Sunday and obtained by HuffPost.

“What’s a guy gota do to get with the hottest girl online tonight,” Eichorn allegedly asked the agent March 11 in response to a fake ad for commercial sex, per the motion.

Their conversation spanned days until his arrest. At one point, the fictitious sex worker revealed her age to be 17, according to the motion. Despite her age, Eichorn asked the fictitious minor for a “naught pic” to prove she was a real person. When the agent sent a photo described in the motion as showing “a clothed female’s cleavage,” Eichorn allegedly asked, “got anything with lot less clothes?”

Eichorn was apprehended by federal agents when he attempted to meet the fictitious sex worker in person, according to the motion.

The politician is now accused of lying about being in possession of a gun and attempting to hide possible evidence in his apartment.

At his court hearing March 20, Eichorn claimed there were no firearms at his St. Paul apartment, the motion said.

Following his arrest, Eichorn made two recorded jail calls to an unidentified woman on March 19 and March 20. On the calls, he discussed getting a new phone number and asked the woman to retrieve a ring that was possibly inside a red bag at his St. Paul apartment, according to the motion.

The woman then replied, “I will grab whatever you need me to grab,” according to the motion.

Federal agents searched the apartment the following day and barred the woman from entering the home, according to the motion. She asked agents if she could retrieve a computer, claiming she used it for her business, but they declined.

Investigators found a red bag containing a handgun and ammunition, along with $1,000, a laptop, SD card, a factory reset iPhone and several of Eichorn’s state Senate business cards, according to the motion.

The attorney representing Eichorn did not immediately respond to a request for comment from HuffPost.

Eichorn resigned from his seat March 20, stating he “must focus on personal matters at this time,” ABC affiliate KSTP reported.

According to court records reviewed by HuffPost, Eichorn’s wife, with whom he shares children, filed for divorce Monday.
